restrict the number of threads MATLAB starts?

On Linux MATLAB R2019b spawns around 150 threads on starting. On our shared servers we limit the number of processess a user can run and thus matlab is crashing. Is there any way to limit the number of threads that MATLAB will spawn?

By default, MATLAB uses the multithreading capabilities of the computer on which it is running.

You can specify the startup option "-singleCompThread" to Limit MATLAB to a single computational thread. This can be done by starting MATLAB program from Linux system prompt using

matlab -singleCompThread

Check matlab (linux) for more startup options.

Alternatively, assign start-up options in the MATLAB .matlab7rc.sh Start-up File. Modifying the ".matlab7rc.sh" file defines start-up options every time you start MATLAB.
