If you forget to load the MATLAB module, then you will get an error when attempting to start MATLAB:

[alice@c4-dev1 ~]$ matlab
-bash: matlab: command not found

Using MATLAB in job scripts #

In order to run MATLAB in jobs, the MATLAB environment module needs to be loaded just as when you run it interactive on a development node. For example, to run the my_script.m script, the job script should at a minimum contain:

#! /bin/bash
#SBATCH --nodes=1
#SBATCH --ntasks=1
#SBATCH --mem=100M
#SBATCH --time=00:02:00
#SBATCH --output=%x-%j.out

module load matlab
matlab -batch my_script.m
