There is one prototype of hptrd
            available, please see below. 
hptrd( MatrixAP& ap, VectorD& d, VectorE& e, VectorTAU& tau );
            hptrd (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SSPTRD, DSPTRD, CHPTRD, and
            ZHPTRD. hptrd reduces
            a complex Hermitian matrix A stored in packed form 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 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.
