I was to run a MATLAB script from the terminal and pass arguments to it. I know I can make it into a function to pass arguments to it but I don't want to make it into a function. Is there a different way? Like can one get the environment variables from the terminal or something as an alternative? As in:

SLURM_ARRAY_TASK_ID = int(os.environ['SLURM_ARRAY_TASK_ID'])
SLURM_JOBID = int(os.environ['SLURM_JOBID'])

as it would be done in python?

"...but I don't want to make it into a function."

Functions have many advantages over scripts (faster, encapsulated functionality, freedom from interference, clear workspace, debugging), which is why experienced MATLAB users write functions and not scripts. Why do you need to avoid writing better code? Why do you want to waste time avoiding doing the one thing that would actually solve your problem very neatly?

A script has access to its caller's workspace. You need not pass anything, they'll just be there.

This also means all variables and changes to variables you make inside the script happen in the calling workspace.

Im running it from the terminal...there is no workspace until the script is called. So it comes from the bash script

You could have your script use the getenv( ) function to retrieve all of those environment variables (as strings). Or have your script call another script as the first action, and that other script does all of the getenv( ) stuff (and perhaps also conversion of string to numeric as desired).
