It shouldn't be too hard to create the interface, if you know a bit of
Lisp and just cargo-cult the existing interface to dgeev and/or
dgesvd.
My knowledge of LISP is zero.
I would do it, but can't right now.? Perhaps in a couple of
weeks?
That's a most generous offer, if you are so inclined. In the meantime, I've found another free interface to LAPACK which somewhat meets my needs for the time being, but the interface is awkward to use. If I had my choice, I'd much prefer Maxima.
