The method is given with a priori error estimate. By using the residual correction procedure, the absolute error can be estimated. Also, one can specify the optimal truncation limit n, which gives better result in any norm. Finally, the effectiveness of the method is illustrated in some numerical experiments. Numerical results are consistent with the theoretical results.
