Suggested April 2024 Synology Mr2200Ac Review: Mesh Router For Advanced Users

Our Verdict

Synology could do a little more to explain the many features of the MR2200ac for first-time users, but the strong performance of this mesh system, and the fine-control provided by its web browser interface make it a good option for business users or home users who have a little more experience of networking technology.

Synology is best known for its DiskStation range of network attached storage (NAS) devices, which are very popular both with business users and more technically knowledgeable home users. However, it also uses its network know-how to produce a range of routers and access points, and is now the latest company to jump on the mesh bandwagon with its new Mesh Router MR2200ac.

Like most mesh networking systems, the MR2200ac routers can be placed in different rooms or locations throughout your home and then linked together in order to provide wider range and higher speeds for your Wi-Fi network than you might normally get from a single conventional router.

And, like most of its rivals, the MR2200ac only acts as a router – it doesn’t include a modem for internet access, so you’ll need to connect it to your existing modem or router in order to carry on using your home broadband.

Price & Availability

Synology sent us two MR2200ac routers to test for this review, but while most mesh systems are sold as kits containing two or three routers the MR2200ac can only be bought as a single, standalone device.

We’ve also seen a wide range of prices for the MR2200ac – most of which are higher than the RRP of £120 quoted by Synology. The MR2200ac is available from Amazon for £160, although one or two online retailers offer it for around £140, so it’s definitely worth shopping around before buying.

Even so, that price isn’t too bad for a high-end tri-band router such as this, and Synology claims that a single MR2200ac should be able to cover homes up to 2000 chúng tôi However, adding a second MR2200ac for larger homes brings the total price to around £300, so it wouldn’t be a bad idea for Synology to offer a more affordable two-piece kit in order to compete with their many mesh rivals.

Synology says that it doesn’t sell the router in multi-packs because it gives the consumer more choice, but we’d still prefer to see a two- or three-pack offered at a discounted price.

For example, our favourite is the  Linksys Velop Dual Band which is £219 for a set of three.

It’s worth mentioning that the MR2200ac is also compatible with Synology’s existing RT2600ac routers. These are faster and even more expensive, at around £240, but can cover chúng tôi each, so that might be a useful option for wealthy football players and the like who need to improve the Wi-Fi in their country mansions.

Design & Features

The MR2200ac isn’t as elegantly designed as some of its more eye-catching mesh rivals, simply consisting of a slim, rather nondescript slab of black plastic, propped up by a small pair of legs that protrude from the base of the unit. However, the router’s upright design does have the benefit of being quite compact, and easy to place on any nearby shelf.

It’s a tri-band 802.11ac router, that uses two 5GHz bands along with the slower 2.4GHz band, to provide a total speed of 2200Mbps for your Wi-Fi network. The router also supports 2×2 MIMO (multiple input/multiple output) to provide reliable data transmission to multiple devices simultaneously.

The router has a WAN port for connecting to your existing modem or router, but there’s only a single extra Ethernet port available for wired connections, which is a little disappointing in a router as expensive as this.

It does, however, include a USB 3.0 port for connecting a printer or storage device that can be shared on the network. We were also pleased to see that the MR2200ac supports Apple’s Time Machine for backing up Macs over the network, as well as FTP and file-sharing services, and DLNA/UPnP for streaming music, photos or video that you may have stored on your network.

Setup

Things got off to a slow start with the MR2200ac, as both the routers that we tested took rather a long time to boot. Synology’s DS Router app does warn that this might take up to three minutes, but our review units took closer to five minutes – and it initially seemed as though the Synology app simply wasn’t working.

And, like Synology’s DiskStation storage devices, the MR2200ac does rely on quite a bit of technical knowledge from its users. As soon as the app detects the router it prompts you to create separate names and passwords for the admin account and network SSID, and asks if you want to set up the router’s QuickConnect remote access features.

That’s a lot to throw at home users who might not have used a mesh router before, and we quickly found ourselves hunting around on Synology’s web site for a proper manual.

Once you’re past the initial installation, the DS Router app does provide access to most of the router’s key features in a more straightforward manner. The app provides a simple network map that allows you to monitor the MR2200ac routers, check upload and download speeds, and to control network access for individual devices within your home.

There’s a SmartConnect option that allows you to separate the 2.4/5GHz bands, or merge them into a single network. The guest network options are handy too, allowing you to activate the guest network for only a specific length of time, or to create a customized schedule for guest access.

The parental controls are quite versatile, with options for setting schedules for internet access and a ‘web filter’ that provides different levels of protection. However, the parental controls aren’t very well explained – in fact the rather jargon-heavy PDF manual that we downloaded doesn’t actually mention parental controls at all – so, again, Synology is taking a little too much knowledge for granted.

Synology tells us that upgrading to the latest version will get you Safe Access which is much easier to use and can do a lot more like creating user profiles to manager devices, internet quota and monitoring internet usage of any user or device.

Performance

It’s not the cheapest mesh router on the market, but the MR2200ac does provide strong performance to justify its price. The first MR2200ac was connected to our existing modem/router for internet access, and devices in the same room showed data speeds jumping from their normal 475Mbps to 650Mbps when connected to the new Synology network.

However, it was the second MR2200ac installed in our back office that showed the greatest improvement. The normal Wi-Fi signal in that office can be rather unreliable, so we actually prefer to use  powerline adaptors to provide a wired connection for our office computers instead. Admittedly, the speeds from the second MR2200ac in the office did still tend to lurch up and down rather erratically, but still averaged out at an impressive 452Mbps during the course of our tests.

Verdict

There’s some things to like about the MR2200ac mesh network such as the strong performance and an excellent level of control on offer.

The downside is that it’s pretty expensive for a single unit when a multi-pack is fairly normal. Synology also needs to make the system more user friendly to appeal to the more casual user at home.

Systweak Advanced System Optimizer 3 Review

Our Verdict

Systweak Advanced System Optimizer 3 is one of the best jack-of-all-trades PC fixers we’ve come across. Though a dedicated AV suite might be more thorough for internet security and a dedicated backup suite might be more flexible, ASO 3 covers all the bases in at least moderate depth and isn’t full of lightweight make-weights.

There are a lot of software applications which aim to keep a PC in trim, by assisting with housekeeping tasks and often offering protection and back-up, too. Systweak’s Advanced System Optimizer 3 (ASO 3) has more parts to it than most and the main control panel offers eight areas of expertise.

Registry Optimizers optimises and cleans the Windows Registry. Disk Cleaner and Optimizers offers a System Cleaner and a start-up optimiser, and Windows Optimizers handles driver updates and sets a PC up for game playing.

Security & Privacy covers protection against AV and malware, controls browser security, and provides file shredding and encryption. A quick malware scan took under half a minute, but a deep scan was slow, taking well over an hour.

Under Backup & Recovery, there’s both file backup and, unusually, system backup, as well as an undeleter which can handle recovery from deleted partitions, as well as accidentally deleted files.

File backup is simple to set up, and you can compress the resulting file into one big 7zip archive.

Backup categories such as Documents or Pictures can be used, but you can also select individual files and folders. A simple scheduler is provided, enabling you to automate one or more backup jobs in a set-and-forget manner. You can’t schedule backups more frequently than once a day, though.

On top of all of these tools sits Smart PC Care, which runs most of the obvious protection scans automatically, to give a rundown of the state of a machine. This is the part you can run for free from the Systweak site.

Systweak Advanced System Optimizer 3: free scan/paid cure

The problem with the free scan/paid remedy paradigm is that software providers try and play up the problems their software has found. For example, most regular PC users wouldn’t consider a tracking cookie much of a threat, though the less-informed might not know what they are and worry unnecessarily when they’re flagged.

ASO 3 does flag tracking cookies, but doesn’t make a big deal of them, just removing them if you tell it. It spots a lot of other things, though, such as adware and spyware, which are worth knowing about and in our tests was above average in deleting or quarantining what it spotted.

We ran the suite’s AV scan on the same 50 GB of files we use when evaluating purpose-made Internet Security suites and it took 2 mins 2 sec to scan 8761 files, giving a scan rate of 71.8 files/sec. A repeat scan looked at the same number of files in the same time, so there’s no noticeable fingerprinting of files. The number of files scanned is at the lower end of those suites we’ve tested, but very similar to dedicated applications from companies like McAfee, Sophos and ZoneAlarm.

Running a scan while copying a 1 GB file took 55 sec; with no scan the same copy took 41 sec, so only a 34 percent increase, which shows a light resource load. In use, ASO 3 is straightforward in layout, with well-structured menus and pop-up dialogs offering three or four options.

Review: Powershell Plus Is A Free Ide For Powershell Users

PowerShell Plus is a very useful tool for anyone using PowerShell and not already strongly invested in a development environment. Now that it’s free, it’s even more appealing.

PowerShell Plus is an IDE (Interactive Development Environment) for PowerShell, which is Microsoft’s high-end scripting/batch processing language. As such, it is focused on the needs of the network admins, DBAs, and so forth, who regularly use PowerShell, as opposed to a more generic IDE such as Eclipse. Idera has released PowerShell Plus—formerly a $200 commercial program—as freeware, with no feature limits, upsells, or other gotchas that sometimes accompany a pay-to-free conversion.

PowerShell Plus offers a clean, easy-to-understand interface that adheres to standard Windows guidelines. There is a good deal of flexibility in which of the many panes and tabs are displayed, and this can be set on a tab-by-tab basis: Each tab open in the main window has its own set of configured controls, so you see exactly what you want to see for each document you edit, within some limits.

Setup and installation are incredibly painless. I’m used to spending some time configuring paths and permissions before I can get a development environment running smoothly, but PowerShell Plus was the epitome of plug-and-play. Granted, I configured it for single-user work and did not have to deal with some of the enterprise-level features, but it was among the easiest installations I’ve ever performed on a program of this type.

PowerShell Plus offers a lot of tools and information, and a user can rearrange or hide most of them as needed.

The function set of PowerShell Plus is solid. All of the expected development features are there, such as multiple editing tabs, integrated debugging, the ability to write extensions to the tool itself using PowerShell, syntax highlight, code completion, and so on. The editor lacks the overwhelming bells and whistles seen in some tools, such as UltraEdit, but it does what it has to do. There are a few odd quirks—although it has an automatic formatter (to get all the braces and indentation lined up), the user can’t define the rules used to format; if you don’t like PowerShell Plus’s code style, that’s that. Another feature I like in an IDE, conditional breakpoints, is not included in this release, but is scheduled to come in the next major release early next year. A free product which is updated with new functionality, also free, is a good buy.

For team development, PowerShell Plus supports several source control systems, including Visual SourceSafe and Team Foundation Server. Likewise, code signing is supporting, allowing users to easily sign code, and to control the execution of unsigned code.

In addition to the usual documentation for the IDE itself, PowerShell Plus includes a link to download a 500+ page PDF that is a teaching guide to the PowerShell language. That is a nice bonus.

A user with an already-configured IDE that provides them all the power and tools they need may or may not find PowerShell Plus offers them either more or better functionality. Since it’s free, there’s little to lose in giving it a spin. Users not already committed to an IDE, or who are dealing with PowerShell via a text editor instead of a development environment, will likely find it a significant improvement.

Note: The Download button on the Product Information page takes you to the vendor’s site, where you can download the latest version of the software appropriate to your system.

Hackers Selling 200 Million Twitter Users’ Emails For $2

The 200 million email addresses are up for sale on Breached, a popular hacking forum. the files can be bought for 8 credits of Breached’s own digital currency, the equivalent of around $2.

There’s little you can do when your email address is circulated like this, aside from keeping your eyes peeled for suspicious correspondence when going through your emails and using strong, unique passwords .

The information is thought to have been extracted via a vulnerability in Twitter’s API that was first exploited to 2023.

Files containing 200 million email addresses belonging to users of the social media site Twitter have been leaked online. They were available for around $2 of digital currency.

The poster claims the files include the same data as the bank of 400 million email addresses that appeared online in November 2023, but with duplicates removed – although those with access to the data say they’ve found duplicates.

Along with email addresses, the files include names, screen names follow counts, and account creation dates (much of which is, of course, public information – just not connected to the email addresses).

Twitter Records Appear Once More

Files full of email addresses belonging to Twitter users have cropped up a number of times on the internet over the past six months or so.

All the data can be traced back to the same vulnerability that was present in Twitter’s API back in 2023, which would effectively allow someone to input email addresses and phone numbers to the site and see if they were associated with a Twitter ID.

The exploit was patched in January 2023, while the news the 5.4 million Twitter users’ emails had been leaked and were up for sale hit the headlines in July.

According to Bleeping Computer, who have confirmed that many of the email addresses listed in the leak are valid, the attackers “used another API to scrape the public Twitter data for the ID and combined this public data with private email addresses/phone numbers to create profiles of Twitter users”.

There are some differences in the data this time round, however, including the fact that the current data did not show whether a user was verified.

What Do I Do if My Email Was Included?

There’s not much you can do about your email being out there. Besides, the average internet user gives their email to so many companies, that this sort of thing can happen at pretty much any time, to pretty much anyone.

Threat actors can use these banks of stolen emails to send malicious links directly to your inbox, or attempt to log into accounts you own in brute-forcing attacks.

In 2023, ensuring you’re alert and staying vigilant when leafing through your email inbox is extremely important. Treat all unverified correspondence with companies through email with extreme caution, especially when they’ve contacted you rather than vice versa.

Use a password manager like NordPass to ensure your password can stand up to any potential brute-force attacks on your accounts. If you take steps like this, you’ll limit what a threat actor can actually do with just your email address.

Best Sig­nal Mes­sen­ger Tips And Tricks For Iphone Users

In a world where privacy violations and data mining have become routine, Signal brings privacy to the table. Undoubtedly, this led to the sudden spike in popularity of the messaging app, thanks to WhatsApp’s new privacy policy agreement. If you are already using Signal on your iPhone, here are some of the best Signal Messenger tips and tricks to help you further secure your data.

1. Turn on disappearing messages

When you enable this feature, the message you send automatically disappear (get deleted) after the set time. It comes in handy if you share an OTP, private number, or something similar. Here’s how to use it.

2. Choose to share or hide read receipts

3. Turn off the typing indicator

This lets you enable or disable the Typing Indicators visible when you or your contact are typing a message. You will find this setting just below Read Receipts (explained above).

4. Turn off link previews

Not generalizing, but I’m not too fond of huge link previews on Slack and other messaging apps. If you, too, do not fancy this, here’s how to turn it off.

Tap your profile picture at the top left.

Tap Privacy.

Switch on or off the toggle for Generate Link Previews.

5. Pin chat on top

Open Signal and swipe left to right on a chat.

Tap Pin.

This person or group chat will stick to the top of the chat screen.

6. Send a ‘view once only’ picture

7. Blur faces before sending

Open an individual or group chat and tap its name at the top.

Scroll to the bottom and tap Block User → Block. They can no longer message or call you.

To unblock, tap your profile picture at the top left → Privacy → Blocked → tap the name → Unblock.

9. Play with Signal stickers

Signal lets you download as well as create stickers for your use. If you love a sticker pack, you may even send it to a friend so that they too can use it. Here’s a full guide about how to use sticker packs in Signal.

10. Change Signal notification sound for a person

Open a chat and tap its name from the top.

Tap Message Sound, choose a different tone and tap Save.

You may follow the same steps for other contacts.

You can also mute chats on Signal for up to one year. You will find this option just below Message Sound (explained above).

I detest this notification as it is irritating and often unnecessary. Here’s how to stop Signal from bombarding you with notifications of your friends joining it.

In the Signal app, tap your profile picture at the top left.

Tap Notifications.

Turn off the switch for Contact Joined Signal.

Now, you won’t see any notification about your contacts joining Signal.

13. Change what is shown on the notification preview

You can also configure what is visible in the chat and call notification when your phone is locked. For this, open Signal and tap your profile picture located at the top left. Next, tap Notifications. Now, tap Show and choose one of the three options:

Name, Content, and Actions: This will show the name and message plus allow you to reply straight from the notification on the Lock Screen or the iOS Notifications Center.

Name Only: The notification will only show the sender’s name but no actual message content. You can not reply to this notification directly from the lock screen or the Notification Center.

No Name or Content: The notification will show ‘New Message!’ No name or anything else. You can not reply to this notification directly from the lock screen or the Notification Center.

14. App Switcher screen security

When you double press the iPhone home button or swipe up from the bottom of the screen and hold, you enter App Switcher. It has cards for all open applications. Many bank apps hide their app preview the moment you enter App Switcher. If you like, Signal lets you do the same.

Tap the profile picture at the top left of the Signal app.

Tap Privacy.

Toggle on Enable Screen Security.

Enter App Switcher, and you will see the blue Signal screen instead of the in-app content preview.

Note: Signal on Android lets you turn on a setting that prevents the other person from taking a screenshot, just like Snapchat. However, as of now, this feature is not on the iOS version.

15. Save mobile data by choosing what is automatically downloaded

Tap your profile picture and choose Data Usage.

Choose the desired media auto-download settings.

To save both cellular and Wi-Fi data, choose ‘Never.’

To save only cellular data, choose ‘Wi-Fi.’

Signal groups have several settings, like who can add members or edit the group information. You will also find the option to create a group link and then send that link to people over WhatsApp, Messages, etc., asking them to join your Signal group. You can access all these by tapping on the group name from the chat screen.

17. Hide your IP address during a call

Want more privacy on Signal calls? Relay calls via Signal’s server. This will reduce the call quality but won’t reveal your IP address to the other person on call.

Go to Signal and tap your profile picture at the top left.

Tap Privacy.

Enable Always Relay Calls.

18. Hide Signal calls from the iOS Phone app

I do not like to see third-party call apps’ entries in my iPhone Phone app. If you feel the same, here is how to change (on or off) this feature for Signal calls.

Inside the Signal app, tap your profile picture from the top left.

Tap Privacy.

Turn off the toggle for Show Calls in Recents.

19. Choose the dark mode for night chats

Tap your Signal profile picture, tap Appearance, and choose either Dark or System (which will follow your iPhone’s dark or light mode).

20. Enable Screen Lock

Often hand over your iPhone to friends and family? Here’s how to lock Signal to keep things extra private.

Go to Signal Settings by tapping the profile picture at the top left.

Tap Privacy.

Enable Screen Lock.

Choose a Screen Lock Timeout option.

Note: If you have not set a passcode for your iPhone and enabled this option in Signal, you may get stuck on the app’s authentication screen. If this happens, open the iPhone Settings app → Face ID & Passcode → and enable passcode for the device. Now, open Signal, enter the iPhone passcode.

Signal now has made it mandatory to set a PIN when you create your account. This PIN protects your accounts and is needed while restoring a local backup, identity verification, etc. Now, to add an extra layer of security, you can enable an option that makes it mandatory to enter this PIN when you set up your Signal account on a different device with the same phone number (or the same account after deleting and reinstalling the app).

For this, go to Signal Settings, tap Privacy, and enable Registration Lock.

22. Clear all chat messages

This will allow you to clear all the text messages, media, calls, attachments, etc., at once. For this, open Signal Settings, tap Privacy, scroll to the bottom, and tap Clear Chat History.

All Signal chats are end-to-end encrypted. But if you still have reservations, you can verify and be extra sure before you share extremely sensitive information.

Open an individual chat and tap its name at the top.

Tap View Safety Number. Here you will see a QR code and a long number.

Ask the other person to follow the first two steps as well.

Now, match the number you see on your screen with that on your contact’s screen. If both numbers are the same, that means the chat between you two is end-to-end encrypted, and no intermediary can snoop in and read your messages.

Tip to ease the verification process: Tap the long number to copy or share it. You can also tap the QR code to launch the camera and hold it over your contact’s QR code to complete the verification.

You may tap ‘Mark as Verified.’ This will show a verified sign below the contact name, giving you peace of mind.

24. Link or unlink chats to iPad or laptop

If you wish to use Signal on your iPad or computer, follow the steps below:

Download and open the Signal app on your Mac, PC, Linux, or iPad. You will see a QR code.

Open Signal Settings on your iPhone and tap Linked Devices → Link New Device.

Scan the QR code and tap Link New Device to link the same Signal account on your other devices.

To unlink: Go to Signal Settings on iPhone → Linked Devices → tap Edit →  red minus icon → Unlink.

Top 24 Signal Messenger Tips and Tricks to Use!

This is how you can get the best out of the Signal app on your iPhone. Currently, the iOS version lacks features like incognito keyboard, creating a local backup, automatic deletion of old messages, note to self, etc., when compared to Signal’s Android app. Nevertheless, it is a fantastic Whatsapp alternative app, and these missing options might soon make it to iPhone as well.

Complete Guide To The Matlab Mesh() With Sample Code

Introduction to Matlab mesh()

The Matlab built-in function mesh() is a 3D plotting function to create 3- dimensional surface plot with respect to the values from the input matrix. The plot generated from mesh() is a surface graphic object which is wireframe parametric by nature. This function maps the input matrix values to color values, generating color maps. The height of the plot depends on the input matrix value, above to x-y plane that can be defined by X, Y coordinate inputs. The color for the plot is determined depending on the surface height.

Start Your Free Data Science Course

Hadoop, Data Science, Statistics & others

Syntax:

This 3D surface plotting function can be implement with different syntaxes depending on input arguments, provided to the function call.

Different syntax and their respective input arguments are described in the below table:

Syntax Description

mesh(Z) It is used to generate 3D surface plot of which x, y co-ordinates are decided by column and row indices of the input matrix ‘Z’.

mesh(Z,C) It is used to generate 3D surface plot for input matrix ‘Z’ with the color for the edges set to ‘C’.

mesh(X,Y,Z) It is used to generate 3D surface plot of which height is determined by the values in the input matrix ‘Z’ and the x-y plane is set by X and Y.

mesh(X,Y,X,C) It is used to generate 3D surface plot of which on the x-y plane, set by X and Y, with edge color ‘C’.

It is used to generate the 3D surface plot with the new axis ‘ax’.

mesh(__,name, value) It is used to set surface properties for the plot using name-value pair argument format.

It is used to store the 3D plot generated from the function mesh() in chart surface object. The object can be used to modify the surface object properties after the plot is generated.

Examples of Matlab mesh() Example #1 – Using mesh(Z)

The below code snippet is used to generate 3D plot for the input matrix ‘I’ which is function of x-coordinate ‘P’ and y-co-ordinates ‘R’ providing ‘I’ as single input argument to the mesh() function call.

Code:

mesh(I)

Output:

The plot is generated with the default color value depending on the data values in the input matrix.

Example #2 – Using mesh(Z, C)

The below set of command is defined to change the color of the same plot generated in the previous function defining the input argument ‘C’.

Code:

colorbar

Output:

The color value is set by the input argument ‘C’ which is being designed as function of the x,y coordinates ‘P’ and ‘Q’.

Example #3 – Using mesh(X, Y, Z)

The code written below generates 3D surface plot from mesh() function which accepts 3 input arguments i.e. input matrix ‘Z’ , x,y coordinate inputs ‘P’ and ‘Q’.

Code:

mesh(P,Q,Z)

Output:

Example #4 – Using mesh(X, Y, Z, C)

The below set of command is defined to change the color of the same plot generated in the previous function defining the input argument ‘C’.

Code:

Output:

The color value is set by the input argument ‘C’ which is being designed as function of the x,y coordinates ‘P’ and ‘Q’.

Example #5 – Using mesh(__,name, value)

Matlab supports the feature to alter the display of the generated plot using name-value pairing format in mesh() function. The attribute given as name in the pair gets set with the data given as value in the function call.

Some of the attributes which can be altered to customize the plot, are given in the table below:

Attribute Description

EdgeColor The attribute is used to decide the color for the edge lines of the plot. Possible values are none, flat, interp, RGB triplets, color name etc.

LineStyle It is used to set the line style for the representation of the 3D surface plot. Possible values are‘-‘ (solid line), ‘- -‘ (dashed line) , ‘:’ (dotted line) etc.

FaceColor This attribute customize the face of the color in the plot. Possible values are flat, interp, RGB triplets, texture map, hexadecimal color code etc.

FaceAlpha It decides the degree of transparency for the faces of the plot. Possible values are any value between 0 to 1.

FaceLighting This attribute is used to decide the effect of the light objects on the plot faces. Possible values are flat, gouraud, none etc.

a. With FaceAlpha=0.6

The transparency of the faces of the plot is resulted with FaceAlpha being set to 0.6.

Code:

mesh(P,Q,R,’FaceAlpha’,’0.6′)

Output:

b. With facealpha=0.8

Code:

mesh(P,Q,R,’FaceAlpha’,’0.8′)

The transparency of the faces of the plot is changed as value for FaceAlpha is updated from 0.6 to 0.8.

c. With Facecolor=flat

Code:

mesh(P,Q,R,’FaceColor’,’flat’)

Output:

The resultant plot is presented with faces having different color for each face depending on the value present in CData property.

The below code returns surface object from the function which is stored in the chart surface object ‘cs’. The display of the plot is altered by modifying the value for EdgeColor and LineStyle by calling the attributes through ‘cs’ object.

Code:

cs.LineStyle=’-.’

Output:

The resultant plot is represented having edges with interpolated coloring depending on the values in the CData property and the lines are displayed following the style format ‘-.’.

Additional Note:

The default behavior of Matlab regarding the plot generation using mesh() function is it computes the color limits depending on the minimum and maximum value of from the input matrix. The intermediate values get mapped to the current color map by means of the process of linear transformation, performed by Matlab.

In the process of generating the surface plot, the simulation of hidden surface elimination is carried out by ‘hidden’ command and that of shading model is controlled by ‘shading command’.
