Orthogonal Factorizations: ScaLAPACK
This section describes the ScaLAPACK routines for the
(QL)factorization of matrices. Routines for the
RZfactorization as well as for generalized
RQfactorizations are also included. For the mathematical definition of the factorizations, see the respective LAPACK sections or refer to [SLUG].
"Computational Routines for Orthogonal Factorizations"lists ScaLAPACK routines that perform orthogonal factorization of matrices.
