NOTES

Any UNIX command can be used from the MATLAB environment by adding an !-mark before the command. For example, to see the time,

>>!date % Will display the time/date

Both MATLAB and UNIX are case-sensitive. Hence, make sure that the CAPS key is NOT locked.

EMAIL program: Try using the email program called "pine" on gamma. It is screen-based and very easy to use.
