There is one prototype of upmtr
available, please see below.
upmtr( const Side side, const char uplo, const VectorAP& ap, const VectorTAU& tau, MatrixC& c );
upmtr (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SOPMTR, DOPMTR, CUPMTR, and
ZUPMTR. upmtr 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 of order nq, with nq = m if SIDE = 'L' and nq = n if SIDE = 'R'. Q is defined as the product of nq-1 elementary reflectors, as returned by ZHPTRD using packed storage:
if UPLO = 'U', Q = H(nq-1) . . . H(2) H(1);
if UPLO = 'L', Q = H(1) H(2) . . . H(nq-1).
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type VectorAP.
The type of values is obtained through the value_type
meta-function typename value_type<VectorAP>::type. The dispatching table below illustrates
to which specific routine the code path will be generated.
