MATLAB is a high-level technical computing language and interactive environment for algorithm development, data visualization, data analysis, and numeric computation. You can use MATLAB in a wide range of applications, including signal and image processing, communications, control design, test and measurement, financial modeling and analysis, and computational biology.

Previously, using MATLAB required a user-supplied license (and a lot of effort) to run on our systems. CAC now has an academic license for MATLAB provided by Queen's University. For a personal MATLAB license through Queen's University, see the ITS software page.

Getting access

Send a signed MATLAB usage statement form to This will add you to the matlab group that allows access to the software. To check if you have been authorized access, type groups while logged on to the system. If matlab appears in the output, you are ready to go!

Running MATLAB

To load MATLAB, use the command module load matlab. If your SSH client supports X-forwarding (and you have logged in using X-forwarding using ssh -X), you can bring up the MATLAB user interface with the command matlab. Note that this may be very slow because our nodes don't have hardware support for the graphics, so that it has to be rendered by the CPU.

To run MATLAB without the GUI use the command matlab -nodisplay

Although MATLAB often used interactively, if you are running a production job, you need to submit it through the SLURM scheduler.

An example of a MATLAB job script is shown below:

#SBATCH --job-name=MATLAB_test
#SBATCH --mail-type=ALL
#SBATCH --output=STD.out
#SBATCH --error=STD.err
#SBATCH --time=30:00
#SBATCH --mem=1000
module load matlab
matlab -nodesktop < testsys.m

Note that a time limit and a memory limit have to be supplied (in the example above 30 minutes and 1000 MByte, respectively). If either is exceeded the job will stop. Standard output and standard error are re-directed to files (STD.out and STD.err, repsectively). Email notification when the job is scheduled and ends are sent to a specified email address. This script (let's call it would thhen be submitted via
