There is one prototype of hetrd
available, please see below.
hetrd( MatrixA& a, VectorD& d, VectorE& e, VectorTAU& tau );
hetrd
(short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSYTRD, DSYTRD, CHETRD, and
ZHETRD. hetrd
reduces
a complex Hermitian matrix A 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 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.
