There is one prototype of hptrd
available, please see below.
hptrd( MatrixAP& ap, VectorD& d, VectorE& e, VectorTAU& tau );
hptrd
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSPTRD, DSPTRD, CHPTRD, and
ZHPTRD. hptrd
reduces
a complex Hermitian matrix A stored in packed form to real symmetric
tridiagonal form T by a unitary similarity transformation: Q**H * A *
Q = T.
The selection of the LAPACK routine is done during compile-time, and
is determined by the type of values contained in type MatrixAP
.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixAP>::type
. The dispatching table below illustrates
to which specific routine the code path will be generated.
