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.
