There is one prototype of pprfs
            available, please see below. 
pprfs( const MatrixAP& ap, const MatrixAFP& afp, const MatrixB& b, MatrixX& x, VectorFERR& ferr, VectorBERR& berr );
            pprfs (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SPPRFS, DPPRFS, CPPRFS, and
            ZPPRFS. pprfs improves
            the computed solution to a system of linear equations when the coefficient
            matrix is Hermitian positive definite and packed, and provides error
            bounds and backward error estimates for the solution.
          
            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.
