matrix math packages for Ada 95

matrix math packages for Ada 95

[Chris Papademetrious]

 Well, here's a good first posting to CLA, I'm about an hour old to
this group. :)

 I'm looking for a source for matrix math packages for Ada 95,
specifically the code required to define a matrix type and allow for
multiplication.  In addition, it would be great to find some code that
does more complicated things like singular valued decomposition, and
even covariance and things of that nature.  *Is* there any code like
this available for reuse?  And if so, why am I not finding it?
 
 I did find a pretty basic matrix package in the PAL, but I was hoping
for something a bit more comprehensive.  Now granted, I'm about four
days new to Ada 95 (coming from a C background), but if I get
anywhere, I'd be happy to make my results publicly available in the
PAL.

 Give a newbie a hand!  :-)

   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 ;-).
