Passing a parameter into a slurm script (matlab)

Question

I am using slurm to submit jobs to the university supercomputer. My matlab function has one parameter:

function test(variable_1)

and my slurm file is (I am not sure if it is correct. I know how to define the value of the parameter in the slurm file, but I would like to pass the value to the slurm file as I need to run the matlab function many times with different values for the parameter):

#!/bin/bash -l

#SBATCH --time=2-00:00:00

#SBATCH --job-name="test"

#SBATCH --nodes=1

#SBATCH --ntasks=1

#SBATCH --mem=4gb

#SBATCH -p small

module load matlab/R2021a

matlab -nodisplay -nodesktop -nosplash -r "test variable_1"

I tried to use the following codes (for example, I would like to set variable_1=12) to submit the job but it did not work.

sbatch  test.slurm 12

Can anyone help me with this issue? Thanks!

You should be using `matlab -batch "test variable_1"`. – Cris Luengo Feb 27 '22 at 14:51 — Cris Luengo, Feb 27 '22 at 14:51

The first argument of the Bash script is stored in an environment variable named $1. So the last line of the script should be

matlab -nodisplay -nodesktop -nosplash -r "test $1"

Beware that if the argument is a number, you might need to first cast it to integer from string with str2num in your Matlab script.

The last part makes no sense. The string is evaluated, and using the command format for calling a function, all arguments are passed in as strings. – Cris Luengo Feb 27 '22 at 14:52
