Choose the root directory of MATLAB

[zaikunzhang]

Is it possible to provide an option that supports a user-defined root directory of MATLAB?

In my project, I would like to modify the xml files under 'mexopts', which is read only. In addition, GitHub actions do not support chmod.

Thank you for your consideration.

You can modify the MATLAB root with setup-matlab@v2-beta, as shown:

name: Run MATLAB Build on GitHub-Hosted Runner
on: [push]
jobs:
  my-job:
    name: Run MATLAB Build
    runs-on: ubuntu-latest
    steps:
      - name: Check out repository
        uses: actions/checkout@v3
      - name: Set up MATLAB
        id: set-up-matlab
        uses: matlab-actions/setup-matlab@v2-beta
      - name: Add file to mexopts folder
        run: touch ${{steps.set-up-matlab.outputs.matlabroot}}/bin/glnxa64/mexopts/my_mexopts.xml
      - name: List files in mexopts folder
        run: ls ${{steps.set-up-matlab.outputs.matlabroot}}/bin/glnxa64/mexopts

Because of the way setup-matlab@v1 works, it is not possible to modify the MATLAB root folder even if we support specifying a user-defined location.

@mcafaro Thank you! It works.
