A few years ago I recall getting the "NAG SCS Ada Library" from my
Ada compiler vendor. I presume not too much has changed in how one
inverts matrices, etc. since then. That was of course pre-web, but
perhaps a search for NAG or Numerical Analysis Group will find it.

I know that the Public Ada Library used to have some linear-a packages,
but the URL I had for it was through AJPO which is now closed. Look
around with a search engine for the Public Ada Library and if you find
them, they'll have the stuff you need.
I think I got a package from Mats Weber at some point in time (maybe
through the PAL?) so you might want to dig around at www.adahome.com and
see if there's anything about it there. (I can dredge around and see if
I can find it if you really get desparate.)

There are bindings to LAPACK
(ftp://cs.nyu.edu/pub/gnat/contrib/lapack-ada), which is available at
netlib( http://www.netlib.org/lapack/index.html)
Maybe this meets your needs.

There is a package from Drexel University
http://dflwww.ece.drexel.edu/research/ada that you may find useful.
There are bindings to LAPACK that may give high performance. I would be
very interested to know if these have been used succesfully with the Sun
high performance libraries.
