There is one prototype of pptrf
            available, please see below. 
pptrf( MatrixAP& ap );
            pptrf (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SPPTRF, DPPTRF, CPPTRF, and
            ZPPTRF. pptrf computes
            the Cholesky factorization of a complex Hermitian positive definite matrix
            A stored in packed format.
          
The factorization has the form A = U*H * U, if UPLO = 'U', or A = L * L*H, if UPLO = 'L', where U is an upper triangular matrix and L is lower triangular.
            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.
