There is one prototype of unmqr
available, please see below.
unmqr( const Side side, const MatrixA& a, const VectorTAU& tau, MatrixC& c );
unmqr
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SORMQR, DORMQR, CUNMQR, and
ZUNMQR. unmqr
overwrites
the general complex M-by-N matrix C with
SIDE = 'L' SIDE = 'R' TRANS = 'N': Q * C C * Q TRANS = 'C': Q*H * C C * Q*H
where Q is a complex unitary matrix defined as the product of k elementary reflectors
Q = H(1) H(2) . . . H(k)
as returned by ZGEQRF. Q is of order M if SIDE = 'L' and of order N if SIDE = 'R'.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type MatrixA
.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixA>::type
. The dispatching table below illustrates
to which specific routine the code path will be generated.
