There is one prototype of labrd
available, please see below.
labrd( MatrixA& a, VectorD& d, VectorE& e, VectorTAUQ& tauq, VectorTAUP& taup, MatrixX& x, MatrixY& y );
labrd
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SLABRD, DLABRD, CLABRD, and
ZLABRD. labrd
reduces
the first NB rows and columns of a complex general m by n matrix A to
upper or lower real bidiagonal form by a unitary transformation Q' *
A * P, and returns the matrices X and Y which are needed to apply the
transformation to the unreduced part of A.
If m >= n, A is reduced to upper bidiagonal form; if m < n, to lower bidiagonal form.
This is an auxiliary routine called by ZGEBRD
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.
