In a similar vein, I have updated my elliptic functions package to
support all 12 Jacobian elliptic functions and their inverses,
and elliptic integrals of the first, second, and third kinds. I tried
to make the names match Macsyma as best as I could without actually
having Macsyma (thanks to Richard Fatement and Barton Willis).
It's basically a major update of ellipt.lisp, which only knew how to
evaluate sn/cn/dn for numeric args.
The package consists of a new ellipt.lisp and a set of patches to
other routines so that tex can print out the standard notation for the
functions, limits can be taken, and converting some special values of
elliptic functions to expressions involving gamma functions. There's
also some rudimentary documentation. No test suite has been written.
I think it would be safe to incorporate since the original ellipt
package was broken (sn(x) would return some junk number, not SN(X)).
If there's interest, I can send it on. It's a bit large, so I didn't
include it here.
