Yes, it was dropped from the distribution because Richard Stallman
tells me that it is a violation of the GPL to distribute code with
Octave that must be linked with proprietary software in order for it
to work.

No, it is not that hard.  You could probably use one of the other
functions like lsode as an example.  But once you are done, you would
not be able to legally distribute it.

I am hoping to find an optimization expert to help provide freely
availble optimization tools.  Would anyone like to help provide
something in this area?
