There is one prototype of ungql
available, please see below.
ungql( MatrixA& a, const VectorTAU& tau );
ungql
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SORGQL, DORGQL, CUNGQL, and
ZUNGQL. ungql
generates
an M-by-N complex matrix Q with orthonormal columns, which is defined
as the last N columns of a product of K elementary reflectors of order
M
Q = H(k) . . . H(2) H(1)
as returned by ZGEQLF.
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.
