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¶

The OnDemand interface for Borah is available at 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
