I've a matlab code that needs to be run for different set of "independent" inputs. I want to run the matlab code through unix bash script, and then run the script in multiple computers parallelly to get the speed-up.

I am fairly new to this. Does any of you have any idea on how to go about it?

在 MATLAB Online 中打开

You need to find your MATLAB command line executable. For Mac it would be /Applications/MATLAB_R2020a.app/bin/matlab . You would invoke it with -nojvm and -nodesktop . With sufficiently new MATLAB releases you might instead prefer to use -batch

/Applications/MATLAB_R2020a.app/bin/matlab -nojvm -nodesktop  %older
/Applications/MATLAB_R2020a.app/bin/matlab -batch

You would then follow that on the command line with a -r option and then the quoted command to execute. It is safest to put the command within try/catch if you are not using the -batch command: For example,

/Applications/MATLAB_R2020a.app/bin/matlab -nojvm -nodesktop -r "try; cd('/Appropriate/Place'); AppriopriateFunction(WithParameters);catch; end; quit"

As an extension to your second argument, can I generate the compiled executable using -mcc command? Upon doing mcc -m mycode.m -o mycode, two files(one executable, another .sh file) get generated. Will that work?
