        vpnorm computes the vector P-norm of _V. The second argument is
        required, and specifies the value of _P.

        A small Rlab program demonstrating the P-norm computation is
        provided below. However, vpnorm is implemented as a builtin
        function for maximum efficiency.


        ________________________________________________________________
        pnorm = function ( V , P )
        {
          return (sum ( V.^P )).^(1/P);
        }
