There is one prototype of pptrs
            available, please see below. 
pptrs( const MatrixAP& ap, MatrixB& b );
            pptrs (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SPPTRS, DPPTRS, CPPTRS, and
            ZPPTRS. pptrs solves
            a system of linear equations AX = B with a Hermitian
            positive definite matrix A in packed storage using the Cholesky factorization
            A = U*H*U or A = LL*H computed
            by ZPPTRF.
          
            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.
