MATLAB¶

MATLAB is a high-level language and interactive environment that enables you to perform computationally intensive tasks faster than with traditional programming languages.

Create a MATLAB Script

First, you need to create a MATLAB script (a .m file) using any text editor. For this tutorial, we'll create a file named myscript.m:
myscript.m
```
% MATLAB Script
disp('Hello, World!')

x = 5;
y = 6;
disp(x*y)
```

Submit your MATLAB job

Create your submission script:

matlab-slurm.sh

#!/bin/bash
#SBATCH -J matlab           # job name
#SBATCH -o log_slurm.o%j    # output and error file name (%j expands to jobID)
#SBATCH -n 1                # total number of tasks requested
#SBATCH -N 1                # number of nodes you want to run on
#SBATCH --cpus-per-task 1
#SBATCH -p bsudfq           # queue (partition)
#SBATCH -t 12:00:00         # run time (hh:mm:ss)


# Load the MATLAB module
module load matlab

# Run the script
matlab -nodisplay -nosplash -nodesktop -r "run('myscript.m'); exit;"

And submit this script using

sbatch matlab-slurm.sh

Check Output

The output of the above job will be saved to a file called log_slurm.o###### where ###### is replaced with the slurm job id. You should see something like the following in the output:
```
Hello, World!
30
```

Using MATLAB in OnDemand¶

Currently OnDemand is available for Borah https://borah-ondemand.boisestate.edu After opening the terminal application on the desktop, here is an example of the commands to open MATLAB:

module load matlab
matlab

And the resulting MATLAB GUI will open in a new window as shown here: Borah OnDemand desktop with MATLAB GUI open
