Module http://www.numeric-quest.com/haskell/Orthogonals.html
has been recently upgraded to handle eigenvectors as well.
With this addition, this is more or less all what I wanted to
have in this module: orthogonalization, linear equations,
eigenvalues and eigenvectors. This is a final version,
and I do not plan bothering you any more with notifications about
further improvements to this module.
Module Evolution is in preparation: it will handle time
evolution of linear systems, including both: classical and quantum
cases.
