There is one prototype of hptrf
available, please see below.
hptrf( MatrixAP& ap, VectorIPIV& ipiv );
hptrf (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines SSPTRF, DSPTRF, CHPTRF, and
ZHPTRF. hptrf computes
the factorization of a complex Hermitian packed matrix A using the Bunch-Kaufman
diagonal pivoting method:
A = UD*U*H or A = LD*L*H
where U (or L) is a product of permutation and unit upper (lower) triangular matrices, and D is Hermitian and block diagonal with 1-by-1 and 2-by-2 diagonal blocks.
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.
