Introduction
MATLAB on Carbon is currently licensed to run on clogin5 only.
Running MATLAB
- GUI, over X11
matlab
- Depending on your network connection this might be rather slow.
- GUI, under VNC
- Follow the general VNC instructions, then start
matlabin the terminal within the virtual desktop. - Command line
- For very slow connections or just basic calculations, you could save some startup time by simply using the text interface. Unset the
DISPLAYvariable before starting matlab.
DISPLAY="" matlab
Troubleshooting
You might get the following errors related to licensing.
Running on a host that is not licensed
License checkout failed.
License Manager Error -9
The hostid of your computer ("001122334455 001122334466") does not match the hostid of the license file (001122334400).
Solution: log in to clogin5 and retry.
License in use
License checkout failed. License Manager Error -9 This error may occur when: -The hostid of this computer does not match the hostid in the license file. -A Designated Computer installation is in use by another user. If no other user is currently running MATLAB, you may need to activate.
Solution: Wait a half hour or so and retry. You can identify the user currently running matlab using the "ps aux | grep matlab" command. Be considerate in negotiating access with that user.
