The DIR command in MATLAB 7.7 (R2008b) allows you to determine the date and time a file was last modified.
The following code returns a struct 'file' which contains a date field for file 'filename.m'.
file = dir('filename.m')
file.date
For more information on the DIR function, execute 'doc dir' at the MATLAB Command Prompt or navigate to the following documentation link:
