There is one prototype of latrd
available, please see below.
latrd( const int_t nb, MatrixA& a, VectorE& e, VectorTAU& tau, MatrixW& w );
latrd
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SLATRD, DLATRD, CLATRD, and
ZLATRD. latrd
reduces
NB rows and columns of a complex Hermitian matrix A to Hermitian tridiagonal
form by a unitary similarity transformation Q' * A * Q, and returns the
matrices V and W which are needed to apply the transformation to the
unreduced part of A.
If UPLO = 'U', latrd
reduces the last NB rows and columns of a matrix, of which the upper
triangle is supplied; if UPLO = 'L', latrd
reduces the first NB rows and columns of a matrix, of which the lower
triangle is supplied.
This is an auxiliary routine called by ZHETRD.
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.
