There is one prototype of hpcon
            available, please see below. 
hpcon( const MatrixAP& ap, const VectorIPIV& ipiv, const Scalar >, Scalar > );
            hpcon (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SSPCON, DSPCON, CHPCON, and
            ZHPCON. hpcon estimates
            the reciprocal of the condition number of a complex Hermitian packed
            matrix A using the factorization A = UD*U*H
            or A = LD*L*H computed by ZHPTRF.
          
An estimate is obtained for norm(inv(A)), and the reciprocal of the condition number is computed as RCOND = 1 / (ANORM * norm(inv(A))).
            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.
