I've tried to compile the file test_generic_complex_eigenvalues.ada
provided in this package (http://www.csee.umbc.edu/~squire/adaclass/
gnatmath95/) but it doesn't compile successfully. And The matrix
package from Drexel doesn't have any eigenvalues/eigenvectors
computation routine at all.

Looking at all this, I'm tempted to say how silly it is that Ada
doesn't provide good numerics capabilities. Ada 05 brought a big
improvement with more vector and matrix operations though it can't
handle the eigenvalues computation of a non-symmetric matrix. The next
version of Ada I read will be out in 2 years. I hope that there will
be better facilities for scientific programming in Ada than there is
today. Those on the Ada community should be made aware of the need for
more scientific computing power in Ada.

There are many libraries for Fortran and C/C++ for numerical
computations while Ada doesn't seem to have a decent one. One cannot
expect people to switch to Ada if there are no good numerical
computing libraries. Ada has been here for more than 25 years now but
maybe has remained confined to military applications for many years.
However free compilers are out there since many years and I hope that
good programmers with good understanding of numerical methods will be
motivated to have bindings for Ada.
