How  EXIT  MATLAB

You  may exit MATLAB after you finished  with  LAB, or in the middle of the work and plan to continue later.

The following steps provide a relatively safe exit:

1. Type:   save var_Filename    See Picture1       Picture 2         
Example : save var_Lab1

This will save your variables in a binary file, that can not be seen, but can be loaded to a MATLAB session.

2. Type: diary off

3. Type exit.
