The svd of it is pretty ugly, but I don't really see why the doubled
eigenvalues should be an issue.. The rooser matrix also has this sort of
problem and I can get that to work fine. In any case, I'm now using the
wilkinson function to generate test matrices, and have eigs fully
working for real symmetric and nonsymmetric problems. I still have an
issue with convergence of complex eigenvalues, that seems to be a bug in
my code as both FreeMat and matlab do not display the same behavior.
Give me a few days and I should be able to release a working version of
eigs..
