Matlab Kernel dead in Jupyterlab

It is the same story for many hours -> close and open Anaconda, Open Jupyterlab, select the Matlab kernel, 2+2 (Shift+Enter], wait 12 seconds -> "No Kernel!"-> Go back to Google and search again. Maybe every Jupyter/Matlab kernel in existence is now installed on my computer and all looks as if it should work. Some guidelines were meant for Linux or Mac. I am on Windows have tried all, of course not on purpose. I probably should have been more methodical from the beginning. Every search query in Google for Matlab including Jupyter is now purple. I would delete all kernels and start over but not sure what I should uninstall first. I prefer not to unistall Anaconda and reinstall. It may be a simple environmental reference from Jupyter to Matlab on my computer but forums do not mention this. I am running the newest student version of Matlab and the newest Jupyterlab. Windows 10 x64 bit. Anyone else having the same problem? Any ideas?

Hi Alan,

It seems like you're encountering a frustrating issue with setting up the MATLAB kernel in JupyterLab on Windows. Let's go through a systematic approach to resolve this problem without having to uninstall Anaconda.

Steps to resolve the issue:

1. Check MATLAB Installation:Ensure that MATLAB is installed correctly and that you can run it independently of JupyterLab.

2. Verify MATLAB Kernel Installation: The MATLAB kernel for Jupyter is provided by the `imatlab` package. First, ensure it's installed correctly:

pip install imatlab

3. Set Up the MATLAB Engine API for Python: MATLAB needs to be configured to work with Python.

4. Check Environment Variables: Ensure that the `PATH` environment variable includes the directory where MATLAB is installed. This allows Jupyter to locate the MATLAB executable.

5. Verify Jupyter Kernel Configuration: Check if the MATLAB kernel is listed when you run:

jupyter kernelspec list

- If `imatlab` is not listed, try reinstalling the kernel.

Hope this helps.
