There is one prototype of ungrq
available, please see below.
ungrq( MatrixA& a, const VectorTAU& tau );
ungrq
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SORGRQ, DORGRQ, CUNGRQ, and
ZUNGRQ. ungrq
generates
an M-by-N complex matrix Q with orthonormal rows, which is defined as
the last M rows of a product of K elementary reflectors of order N
Q = H(1)' H(2)' . . . H(k)'
as returned by ZGERQF.
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.
