There is one prototype of pptri
            available, please see below. 
pptri( MatrixAP& ap );
            pptri (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SPPTRI, DPPTRI, CPPTRI, and
            ZPPTRI. pptri computes
            the inverse of a complex Hermitian positive definite matrix A 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.
