The strange thing is that 2 days ago it all worked.

I do not have a big knowledge of bash, so please be more explicit you can.

I have also an other question: is there a way to launch the code without obtain the intial MATLAB text on the terminal (below)?

MATLAB is selecting SOFTWARE OPENGL rendering.

Greetings Fedor,

I see that you’re facing an error when trying to run MATLAB from bash.

Here are a few pointers to keep in mind:

1. Use just the name of your script without the ".m" extension.
2. When automating MATLAB scripts, please use the “-batch” flag. The initial MATLAB text will be hidden from the output in this mode.

Your bash command would then look something like this -

matlab -batch "try; name_of_matlab_script; catch; end; quit"

You can learn more about starting a MATLAB program from the Linux terminal here: https://www.mathworks.com/help/matlab/ref/matlablinux.html

Furthermore, the error you've encountered is benign and is fixed since R2022a. Please update your MATLAB version to fix this error. Read more about this here: https://www.mathworks.com/support/bugreports/2613427

I hope this helps.

Thanks & regards,

Suraj.
