Install the extension in VS Code

• Open the command palette using Ctrl+Shift+P
• Type ext install Matlab in the command palette

Select MATLAB as a language

• On the bottom-right corner, click on the select language mode button, if you have created a new file it should display Plain Text
• Select MATLAB in the list of languages.

Alternatively, saving the file with a .m extension, will allow VS Code to understand that it is a MATLAB file, and automatically select the language correctly.

Using snippets

• Bring-up the autocomplete menu by hitting the Ctrl+Shift key combination
• Select the snippet that you want to use in the list
• Use tab to navigate trough the snippet's variables

Setting-up linter

• Open the User Settings by going to File>Preferences>User Settings

• On the right pane, where you have the settings.json file open, add to the json file.

  "matlab.mlintpath" : "path to your mlint.exe file"

  For example, on a PC :

  "matlab.mlintpath": "C:\\Program Files (x86)\\MATLAB\\R2012a\\bin\\win32\\mlint.exe"

  And on a Mac :

  "matlab.mlintpath": "/Applications/MATLAB_R2016a.app/bin/maci64/mlint"

• Save your settings.json file

• Now, when you open a Matlab document (.m), VS Code displays warnings and errors.

  Remark: If you don't want the lint on save option and you want to remove the error message being displayed when the extension activates, change the matlab.lintOnSave option in the settings file to False.

Changing the default file association

Visual Studio Code's default file association for .m files is Objective-C, if you want to setup the default file associationt to be Matlab go to the Users preference (File>Preferences>User Settings) and add the following line:

"files.associations": {"*.m": "matlab"}
