interactive matlab via X11 tunnel - GUI (mac/linux)

This is the "regular" way to use it, it pops up a GUI.

ssh -X corn.stanford.edu
module load matlab
matlab

If your X11 forwarding is configured correctly, it will pop up the MATLAB gui on your display.

If it's a newer Mac, you may need to install XQuartz and reboot your machine and then "-X" automatically starts XQuartz for you.

If you don't have X11 forwarding enabled, you'll get an error message like this:

 Warning: No display specified.  You will not be able to display graphics on the screen.

and then you get the cli interface.

You may also get an error like

 /usr/bin/xauth:  timeout in locking authority file /afs/ir/users/c/h/chekh/.Xauthority

That means something went wrong with your login, try again? Maybe try a 'kdestroy' on your machine, or else configure your SSH client for GSSAPI per Advanced Connection Options.

interactive matlab - CLI

If you want the cli interface, just use 'matlab -nodesktop'.

If you want a single-threaded matlab, use something like

 matlab -nosplash -nodesktop -nodisplay -singleCompThread

interactive matlab via VNC - GUI (all platforms)

If you setup a VNC session as described here you can run run matlab in a full desktop environment. This has the advantage that you can connect and disconnect at will without disturbing your running matlab.
