Probably not: ,----[ (info "(gsl-ref)Eigensystems") ] | This chapter describes functions for computing eigenvalues and | eigenvectors of matrices. There are routines for real symmetric and | complex hermitian matrices, and eigenvalues can be computed with or | without eigenvectors. The algorithms used are symmetric | bidiagonalization followed by QR reduction. | | These routines are intended for "small" systems where simple | algorithms are acceptable. Anyone interested finding eigenvalues and | eigenvectors of large matrices will want to use the sophisticated | routines found in LAPACK. The Fortran version of LAPACK is recommended | as the standard package for linear algebra. `---- Greetings, Jochen -- Einigkeit und Recht und Freiheit http://www.Jochen-Kuepper.de Liberté, Égalité, Fraternité GnuPG key: CC1B0B4D (Part 3 you find in my messages before fall 2003.)
