Try "Numerical Recipes in Pascal" by Cambridge University Press.
( 40 West 20th st. NY ). (Probably available at your local good bookstore
but the publishers have the routine on disk.)
I use the "C" version and it is extremely good. A few little bugs
like the way they sometimes address arrays (nothing I have found
that would cause the programme to crash though). It has a suite
of programmes for eigensystems. The methods are very well thought out
and go far beyond the ususal simple approaches, so that the performance is
optimum.
