This MATLAB version MD5 is for checksum of files and strings. The speed is very fast. A timer shows time taken to finish the process in seconds.

Just type: mMD5('filename') for a file or mMD5('string') for a string, eg., mMD5('abcd').

That is a good point to have the MD5 sum output stored in a string. The file has been updated. To use this function, just do:
% for a file:
a = mMD5('contents.m')
or
% for a string:
a = mMD5('abcd')
the MD5 sum now is saved in variable a.
