There is one prototype of ppcon
            available, please see below. 
ppcon( const MatrixAP& ap, const Scalar >, Scalar > );
            ppcon (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SPPCON, DPPCON, CPPCON, and
            ZPPCON. ppcon estimates
            the reciprocal of the condition number (in the 1-norm) of a complex Hermitian
            positive definite packed matrix using the Cholesky factorization A =
            U**H*U or A = LL*H computed by ZPPTRF.
          
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.
