I think it would be good to get these functions in Octave, and
reconcile any differences.

Based on what I just found with stem, I would be surprised if the
functions from OctPlot could just be dropped in to the Octave source
tree.  In addition to the differences I mentioned a few moments ago in
another thread, take a look at the version of stem.m that is now in
the Octave CVS archive to see the other kinds of changes I would like
to see before these functions are added to Octave.

Thanks,
