There is one prototype of ptcon
            available, please see below. 
ptcon( const VectorD& d, const VectorE& e, const Scalar >, Scalar > );
            ptcon (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SPTCON, DPTCON, CPTCON, and
            ZPTCON. ptcon computes
            the reciprocal of the condition number (in the 1-norm) of a complex Hermitian
            positive definite tridiagonal matrix using the factorization A = LD*LH or A = U*H*D*U
            computed by ZPTTRF.
          
Norm(inv(A)) is computed by a direct method, 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 VectorD.
            The type of values is obtained through the value_type
            meta-function typename value_type<VectorD>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
