I am not able to figure out how to run MATLAB (.m) code in VSCode.
I have installed the MATLAB Extension for VSCode and added the path for the mlint file for MATLAB as stated in the extension.
"matlab.mlintpath"
VSCode identifies the file as a MATLAB file. However, the code won't run.
How can I run MATLAB code from within VSCode?
There is a way, this VSCode extension suggests that you can use it to run MATLAB code from within VSCode without having to open the MATLAB GUI. It does not invalidate the below though; you need to have a working, licensed MATLAB installation, which will be called in the background. Without a working, licensed MATLAB installation you cannot run MATLAB code.
As MATLAB is proprietary, there are only two ways to run MATLAB code: by running the code from the MATLAB IDE (with a valid license of course), or by compiling it to an executable file with the MATLAB compiler.
You might be able to get other IDEs to have syntax highlighting and typing-hints like MATLAB's own IDE through importing its mlint functionality, like you did, but that won't execute the code.
Thus no, you cannot execute MATLAB code directly within VSCode, you can only covertly call the MATLAB engine from inside VSCode.
A possible workaround would be to export your MATLAB code to C/C++ using the MATLAB Coder. You can then run the C/C++ code from within VSCode.
TL;DR:
I wrote Matlab Terminal Extension for VS Code on Linux. It can run matlab files and spawn a matlab-Terminal. You can find the repo here.
MatTer for VS Code
I recently wanted to used a matlab terminal in vscode. There even is an extension for this. But while using the extension I faced some flaws. Also the repository does not seem to be active anymore and the owner doesn't react to issues and similar.
So I decided to write my own first extension MatTer for VS Code and published it to the VS marketplace. It's in early Development, but it can already spawn a matlab-Terminal and run matlab files.
The repo is hosted on Github, see here: https://github.com/mauzigoe/matter-for-vscode
To install it via vscode just search for matter-for-vscode in Extension.
Critics and Feedback is welcomed, esp. since I'm new to this.
"#Liam the long discourse is necessary, because having the extension without a valid MATLAB license+installation won't work.T"
...because at some point you need at least ONE working matlab install just to develop the m-file :)
I suspect that you're right, and it comes down to a choice between embedding "foreign" code into an m-file, or making calls to the matlab engine from within a foreign IDE. They do have a free RTE but you still need some form of Matlab IDE to write in plus the Matlab Compiler toolbox to build the project out for the RTE.
The work-around is to use OS tools to remove Matlab and other proprietary tools from the loop entirely. That is why if you're going to be forced to pay $5k for a proprietary tool, it has to be justified in other ways than "it can get the job done".
VS Code extensions have the same problem as any other extension: if you look at the repository and see what is required to install and run the extension? You'll probably never install an extension again. It's about as wise as blithely downloading and installing any code from the Internet: it's no better than the source. I would wait until you figure-out how to call getOpen() etc within VS Code without downloading some random extension from some random source especially one that hasn't been updated in the past 2 years. Or at least use VS2019 Community:
https://www.mathworks.com/matlabcentral/answers/100603-how-can-i-compile-a-matlab-engine-application-using-microsoft-visual-studio-9-0-or-10-0
you could use the "Matlab Interactive Terminal" Extention, the link is below.
To use it, you need to follow the instruction to install a "MATLAB Engine API for Python" and you are good to go (and you need a working Matlab).
after installing the extension, you could open the Matlab terminal in the command window (by pressing Ctrl+Shift+P and input "Open a Matlab Terminal"), and you could get the same Matlab terminal as in the real Matlab IDE, and now you could run .m code in Vscode.
You can use the Code Runner extension and put this line in your settings.json:
"code-runner.executorMapByFileExtension": {
".m": "cd $dir && matlab -batch \"$fileNameWithoutExt\""
}
You would probably also want to install the MATLAB extension.

Is it possible to configure vs code to support the ZMODEM protocol? I could use xshell to download files with sz command, but when I try to use sz in vs code, here it returns some random number.
(base) [alpha#hpc03 newfile]$ sz INCAR
�*B00000000000000
I use Remote-SSH extension in vs code to connect to the Linux system.
My question is:
Is there any extension or configuration method that would allow me to use sz in vs code?
As far as I know (I looked, didn't find anything) there's no existing extension or method to use the ZModem protocol with VSCode. However, there's a pull request from 2017 that adds support for it to Xterm, which is the terminal display VSCode uses. As indicated in this mentioning issue the VSCode developers would need more information.
As far as an extension goes, if you or anyone reading this wanted to make an extension for this purpose, you could use this ZModem.js implementation of the protocol in Javascript, and write the extension yourself, or do something similar.
From the Remote-SSH docs
VS Code will look for the ssh command in the PATH. Failing that, on Windows it will attempt to find ssh.exe in the default Git for Windows install path. You can also specifically tell VS Code where to find the SSH client by adding the remote.SSH.path property to settings.json.
Maybe you can include Xshell somehow this way. Or find a windows version of zssh (not this from the Ziti project) and it could work. Another candidate is SecureCRT. (via). Probably these rich GUI apps are not embeddable as simple CLI programs, though. Which would be a useful feature in this case.
I just installed VSCode 1.59.0 along with the Julia, Jupyter, and Python extensions. I am able to create Jupyter notebooks using either Julia or Python. When I create a notebook using Python, I see the variables I create listed in the Jupyter: Variables tab. When I create a notebook using Julia, however, I do not see the variables I create listed anywhere.
At the present moment, while Julia is generally supported in the VS Code Extension, this specific feature is not supported. I have an issue on the Microsoft side and Julia VS Code side open here: https://github.com/microsoft/vscode-jupyter/issues/7224 to hopefully kick start this process.
The Julia VS Code extension does already support this feature outside of Notebooks (when running a ".jl" file) so this should seemingly not be too difficult of a task to port it over to the Jupyter extension, but I am unfamiliar with the level of technical rigor this would require.
I recently got a new computer and reinstalled visual studio code but I haven't been able to run any of my files. The error has occurred with both python and C++, so I feel as though it is the IDE that is the problem. I have looked online and there are no straight answers as I have tried following some solutions which have resulted in different errors.
The error above comes up when I run (F5) a simple line of code in c++. Does anyone have a solution?
Thanks, Jacob
[EDIT]
For my python files to work I have to manually select 'Python: current file' but for c++ files they still have the same error.
First step, uninstall python from this machine.
Second, reinstall and make sure that you check the box "add to path".
It's pretty easy to miss as it's a small box, and I missed it my first time installing python earlier in the year. Here's the box you may have missed while installing.
It could be your extensions.
I had a similar error message and simply updated all of my extensions and then my SDK. I was then able to run my code within the IDE. I was using VSCode for c++ and also updated my GCC compiler along with the extensions.
Also look into your computer's environment variables, if you have changed the %PATH variables it may be affecting your ability to run/compile programs.
I am studying economics so I have not much experience in programming. I really would like to make Julia work on Visual Studio Code but I've been unsuccessful.
So I downloaded the Julia extension but I don't know how to define the settings. Do I need to create a launch.json file or any other file to make it work?
I think that somebody asked a similar question previously at "How to setup Julia in VS code?"
but the answer didn't really help me.
Thank you all for your help.
First you need to install Julia on your Mac by downloading the julia dmg file from here. This puts an application in the Applications folder.
There are several ways to set things up so julia will run from command line. I used the following:
ln -fs "/Applications/Julia-0.6.app/Contents/Resources/julia/bin/julia" /usr/local/bin/julia
This should work if the name of your application, that you just installed, is julia-0.6.app
After running the above command, you should be able to type Julia on the command line and have it to start.
You can now create a Julia script and place it in the directory you're running from. I created a file named julia_test001.jl It contained the following:
for i in 1:5
print(i, ", ")
end
This is a very short Julia script I wrote for testing.
Now start VScode and install the Julia language support extension. After that has loaded, open the file Julia_test001.jl. Once this file is opened, click the triangle in the upper right corner or open the command palette and select the option: run code. The julia_test001.jl should run and print the result 1,2,3,4,5.
I'd like to use VS code with the 'MATLAB Runner' extension. I have updated my 'user settings' json file according to the instructions:
but when I try to run code, I get the following error:
Could not find path to the matlab executable.
What's wrong?
It appears that you're using MATLAB R2016a on Windows. This is unfortunate, as the readme for "MATLAB Runner" clearly states that:
Please Note
This extension works best on mac as Matlab does not fully support running the executable from command prompt. Also, versions prior to 2017 will not work on windows at all.
Thus, if you insist on using the plugin, you should update your MATLAB version or switch operating systems.
