Information-theoretic functions

Hello there,
I have a followup email to this discussion at,
http://www.cae.wisc.edu/pipermail/octave-sources/2006-November/000048.html

I have put the files contributed by Joseph Wakeling, into a form we can add
to our repository. But, can I put a GPL on it, and commit? or the license I
have to wait for Joseph's consent?

I have written to Joseph, but waiting for his reply.

Thanks,
Muthu
