QuickStart MATLAB

MATLAB is short for MATrix LABoratory high-level language and interactive environment.

  • $ module avail MATLAB

  • $ module load MATLAB

    Note: default version is MATLAB/R2020a

    Please note, the module load command is case-sensitive.
    If you don't include a version, the default is loaded.

  • $ interact
    Note: the default options will reserve 1 node with 1 cpu for 1 hour.
    You can use interact --help to learn how to configure the script.

    Within an interact session, you can load matlab and test your matlab code.

    $ load MATLAB
    $ matlab -options   < input-file  > output-file

    Note: you can check the available toolkits in a running matlab session with var.

    Note: once your testing is complete, exit your interact session before submitting your qsub reservation.

  • #!/bin/bash
    #PBS -l nodes=1:ppn=1
    #PBS -l walltime=10:00:00
    #PBS -m abe
    #PBS -M your_email@kennesaw.edu
     
    JOBID=`echo $PBS_JOBID | cut -f1 -d.`
     
    module load MATLAB
     
    # Create a temp workdir under scratch
    mkdir -p ${HOME}/scratch/matlab
    export PBS_MATLAB_WORKDIR=$( mktemp -d -p ${HOME}/scratch/matlab workdir_XXXXXXXXXX )
     
    matlab -nodisplay -nosplash -logfile ${FILE}.log -r "run ${FILE}"
     
    # Delete temp workdir
    rm -rf ${PBS_MATLAB_WORKDIR}
    Note: reservation is for 1 node with 1 cpu from the batch queue for 10 hours.

    Usage:  qsub run_matlab.pbs -vFILE=${PWD}/matlab_script.m
    Note: If you use the interact script, exit out before submitting with qsub.
