Can I modify files with copyrighted by The Mathworks?

Some functions provided by MATLAB (genpath, for example) list a Copyright notice. Can I modify these to add capabilities and then resubmit them to the file exchange? If so, how should they be marked?

While I know the answer is No, I would love to hear solutions about what should be submitted to the FEX in these cases. In a number of cases I am using "patched" version of copyrighted functions. In a few cases the functions need to be directly overloaded (e.g., tex.m and subplot.m) while in most cases new file names are fine.

Some years ago, Matlab's filtfilt.m function could be accelerated massively by modifying some lines only. I did not submit the changed version to the FileExchange due to the copyright, but the function, which applied the modifications automatically. I asked TMW, if they agree with this solution.
Later on Matlab's original function has been improved also and I've removed this tool from the FEX.
