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