How can I add an expiration date and time to my script or P-code file?

Hello,

I have a MATLAB script code which I have it converted into a P-code file, using "%pcode*.m". I wanted to share my P-code file with a friend with an expiration date. May I please get help on how to add an expiration date and time to my script?

Thanks,

One way that you could do it would be to put a line in your *.m file code that checks the date [using, for example, the now() function], and returns with with no result (or an error message) if it is past the expiration date.

This could presumably be foiled if they manipulate their system clock, though.
