About central difference-techniques in solving SpBVps

In this paper, a numerical comparison of four difference-techniques recently developed by Algelani and El-Zahar [5, 7] in solving linear SPBVPs is presented. First, the order of convergence of the difference-techniques developed in [5] is estimated. Then these four central difference-techniques are applied to SPBVPs and the numerical results are compared with other difference-techniques in the literature. The numerical results confirm the theoretical ones and show that the above techniques result in an accurate solution of SPBVPs.
