Ada is excellently apt for numerical software.
I wrote a little publication for the OOP 97 (in german, "Numerische und
symbolische Mathematik mit Ada 95"). There are some 30000 lines of code
showing the use of Ada for state space systems and numerical integration
and for symbolic mathematics. The software as well as the documentation
(180 pages in german) are freely available from the following source:

ftp://cci.de/pub/Ada/Numeric/         oopmath.tgz  &  read.me

There are a some generic packages for simple linear algebra like
vectors and matrices. In the 80's at the university of paderborn a group of
4 students / assistants also implemented a subset of the linpack/eispack
algorithms in Ada 83, especially linear algebra, svd, eigenvalues. This
software is well tested and still is used in the institute for controller
design
and nonlinear simulation. It's not yet on any public internet server, but
the
leader of the institute (Prof. Dr.-Ing. J. L�ckel) allowed to make it
public.
I want to sort the Ada 83 packages into my new Ada 95 package
hirarchy before making them available, but seldom have time for that
task.
