MATLAB kernal for vscode-jupyter

[p1um3r]

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

I can't start the MATLAB kernal for vscode-jupyter.
However, I can start a jupyter notebook server first and then connect to the exsiting sever successfully.
I hope that someone could sovel my problem

associated add support for matlab

[DonJayamanne]

@p1um3r Can you try installing matlab in a virtual environment and see if you still run into this same issue?
Also, please can you share the install steps for matlab (that you have used) on Windows
