How do you run Matlab in batch mode in R2021b Update 2?

Hi,

I would like to run a bash script in matlab without GUI.

In version R2020b, it was working, now (R2021b Update 2) it is not.

xy@host:~/dev/$ matlab -batch "compile_lib.sh"

MATLAB is selecting SOFTWARE OPENGL rendering.

>> exit

Also tried: matlab -nodisplay -nosplash -nodesktop -r "run('compile_lib.sh');exit;"

But the output is the same as above.

Could you tell me what is the correct method to do this?

The run() command required the name of a Matlab script. "compile_lib.sh" does not sound like a Matlab script file name.

Hi Jean,

To run a bash script, you don't need MATLAB. You can just open terminal and execute the following command:

bash compile_lib.sh

If the script is a MATLAB script (.m file), then you would execute it without opening the GUI using the "run" function. The following is the documentation link:

https://www.mathworks.com/help/matlab/ref/run.html

If you still want to execute bash script using MATLAB only, then you can use the "system" function to do it:

matlab -nodisplay -nosplash -nodesktop -r "system('bash compile_lib.sh');exit;"
