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. That stuff is available by
anonymous ftp from:
   methan.chemie.fu-berlin.de [130.133.2.81]
   directory: pub/math/matrix     file: cplx_mat.tar.Z

There is no warranty whatsoever for these procedures.
