I placed an update to orthopoly at
http://www.unk.edu/acad/math/people/willisb/
User documentation is here
http://www.unk.edu/acad/math/people/willisb/orthopoly_doc.html
Some things I've added and fixed since the previous version:
(a) gradef for pochhammer,
(b) makegamma support for pochhammer,
(c) a new function that gives recursion relations,
(d) a new function gives the integration weights,
(e) additional user documentation,
(f) fixed a few bugs (see changes_0.9_to_0.93.txt)
(g) additional tests.
Notes:
(a) I also added makegamma support for genfact; I need to check the
source for
genfact to be sure I did it correctly. (Maxima user documentation doesn't
say
what genfact does when its 2nd argument isn't an positive integer. I'm
not sure
my makegamma works in all cases.)
(b) Version 0.93 is preliminary. Expect bugs.
(c) The archive contains a file orthodisc.lisp that is a start on a future
enhancement; it
will not be a part of version 1.0. I haven't tested this code.
