How to Run a Matlab function using .sbatch file

Hi I am new to slurm and I am trying to run a MATLAB function (I cannot use MDCS because that apparently is not available on one of my available HPC clusters)

I think I am having trouble with understanding the appropriate notation for running a script vs a function using slurm.

These are the two pieces of code that I have seen:

matlab -nodisplay < multi_parfor.m

and...

matlab -nodesktop -r "multi_parfor.m" 

I was wondering if anyone could explain how to do this, and maybe make a comment on the use for each of the above lines of code (is one for a script and one for a function? etc).

Thank you in advance

You can pass the input arguments for a funtion like this:

srun matlab -nodisplay -singleCompThread -r "FunctionFileName(INPUTArg1,INPUTArg2,INPUTArg3)" 

If it is just a script, and not a function, this is how you would write it:

srun matlab -nodisplay -singleCompThread -r "ScriptFileName"

Compute Canada documention has a clear outline on how to write a Slurm submission script to submit a MATLAB job:

And this matlab documentation outlines the syntax/commands of the line above:
