I appreciate it. > >Erik Schumacher >Optical Sciences Center >University of Arizona Well, I have translated a set of Algol procedures which appeared in Numer. Math. (in the 1960s) to the C language. The routines for the diagonalization of Hermitian matrices are based on the Householder-Givens method.
