=Interactive Session - GUI=
To use the MATLAB graphical user interface (GUI) remotely, you will need to enable X11 forwarding over SSH by adding -X (Note: X is capitalized) to the ssh command when logging into Magnolia.

{{Cmd|ssh user@magnolia.usm.edu -X}}

Once on Magnolia, start an interactive bash session by running the srun command below. This will create an interactive session on the float partition that uses two processors with a time limit of three hours. The --x11 flag has been added to enable X11 forwarding.

{{Cmd|srun -p float -n 2 --pty --x11 -t 03:00:00 bash}}

Then make sure that you are not on one of the head nodes (magnolia01/magnolia02) and load the matlab module into the environment. Once this is complete, simply type matlab into the prompt and the GUI should appear on your desktop.

{{Cmd
|module load matlab
|matlab
|output=
<pre>
MATLAB is selecting SOFTWARE OPENGL rendering.
