There is one prototype of unghr
available, please see below.
unghr( const int_t n, const int_t ilo, const int_t ihi, MatrixA& a, const VectorTAU& tau );
unghr
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SORGHR, DORGHR, CUNGHR, and
ZUNGHR. unghr
generates
a complex unitary matrix Q which is defined as the product of IHI-ILO
elementary reflectors of order N, as returned by ZGEHRD:
Q = H(ilo) H(ilo+1) . . . H(ihi-1).
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.
