Abstract
In a recent paper, Noor and Noor [K. Inayat Noor, M. Aslam Noor, Predictor-corrector Halley method for nonlinear equations, Appl. Math. Comput., in press, doi: 10.1016/j.amc.11.023] have suggested and analyzed a predictor-corrector method Halley method for solving nonlinear equations. In this paper, we modified this method by using the finite difference scheme, which has a quintic convergence. We have compared this modified Halley method with some other iterative of fifth-orders convergence methods, which shows that this new method is a robust one. Several examples are given to illustrate the efficiency and the performance of this new method. (c) 2006 Elsevier Inc. All rights reserved.
