Polar Grid Matlab Note

If you get the error

[matlab@polargrid003 ~]$ /usr/local/matlab/bin/matlab
Warning: Unable to open display , MATLAB is starting without a display.
You will not be able to display graphics on the screen.
License checkout failed.
License Manager Error -95
MATLAB is unable to connect to the license server.
Make sure you can resolve the hostname of your machine.
If you are unable to resolve the hostname, contact your System Administrator.

Troubleshoot this issue by visiting:

Diagnostic Information:
Feature: MATLAB
License path: /usr/local/matlab/etc/license.dat:/usr/local/matlab/etc/*.lic:
FLEXnet Licensing error: -95,378. System Error: 115

This just means that the matlab license server isn't running. Start it as the matlab user with the command

/usr/local/matlab/etc/lmstart -l /tmp/eeee
