   There's an Ada binding to the LAPACK library  (all you can dream of
when you're thinking about linear algebra, in Fortran), available at :

   ftp://cs.nyu.edu/pub/gnat/contrib/lapack-ada

   You'll  also  need to download  a  few libraries  and  manuals, but
everything is explained in  the README and INSTALL  files. This is the
work of Wasu Chapanon.

   Some  people with strong  Fortran  background have recently  showed
their interest in Ada 95 as a  new language for numerical computations
: good software engineering  capability and easy interface to existing
Fortran code (including   support for Fortran  convention on  arrays),
plus a  well defined numerical model. So  may be some material in this
area will appear soon (I hope so ;-).

   Hope this helps,
