There is one prototype of gehrd
available, please see below.
gehrd( const int_t ilo, const int_t ihi, MatrixA& a, VectorTAU& tau );
gehrd
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SGEHRD, DGEHRD, CGEHRD, and
ZGEHRD. gehrd
reduces
a complex general matrix A to upper Hessenberg form H by an unitary similarity
transformation: Q' * A * Q = H .
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.
