Like several have already said, if you're doing numerical work - you
should use something besides the matrix lib in the stdlib.

For yet another working suggestion, NArray has an extension to do
eigenvalues and eigenvectors based on lapack.

  http://narray.rubyforge.org/
  (ext is called na_geev, it's also available on that page)

It's worked for me.
