Matlab is distributed with a certain amount of M-files which would 
be covered under their licensing.  I don't think they can legally 
stop someone from reverse engineering a _data_ file produced
by Matlab (yet), unless they own the data.  In other words, if
I filter a few meg of data that I own through matlab, then the
data in the output should still be my property and reverse
engineering should be legally admissable.  If this is not the 
case, it would shut down several reverse engineering projects
such as wine, etc.
