There is one prototype of hecon
            available, please see below. 
hecon( const MatrixA& a, const VectorIPIV& ipiv, const Scalar >, Scalar > );
            hecon (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SSYCON, DSYCON, CHECON, and
            ZHECON. hecon estimates
            the reciprocal of the condition number of a complex Hermitian matrix
            A using the factorization A = UD*U*H
            or A = LD*L*H computed by ZHETRF.
          
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 MatrixA.
            The type of values is obtained through the value_type
            meta-function typename value_type<MatrixA>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
