Yes, when I run it directly, the script finishes, exits, and returns to the MATLAB command prompt. I can them manually quit with no problem. The problem is that the driving shell script doesn't know the code is finished because MATLAB just sits idle instead of exiting. What I need to be able to do is to exit MATLAB from within an executing MATLAB program or something like that (ie: exit the program and then exit MATLAB automatically). Thanks for the help.
