Are you talking about what is posted at http://www.atmos.washington.edu?

I haven't looked at the code, but is it an independent implementation
for Octave or was it written for Matlab?  Given the name of the
directory and the list of files in the directory, it looks like
someone has made some version of the Matlab control toolbox available
on the web.  Somehow, I suspect that the MathWorks would not approve.
As I recall, redistribution is not allowed by the license.  If it is
MathWorks code, then even if you have a license for it, you can't
simply modify it until it works in Octave and then submit it to the
Octave project.  Doing that would clearly be a copyright and license
violation.
