Orthogonal Factorizations: ScaLAPACK
Computational Routines
This section describes the ScaLAPACK routines for the
QR
(RQ)
and
LQ
(QL)
factorization of matrices. Routines for the
RZ
factorization
as well as for generalized
QR
and
RQ
factorizations are also included. For the mathematical definition of the
factorizations, see the respective LAPACK sections or refer to [SLUG].

Factorizations"
