摘要
提出了求解非线性方程根新的四阶收敛迭代方法,新方法每次迭代只需要两次函数计算,一次一阶导数值计算,效能指数达到1.587.通过几个数值算例来解释该方法的有效性.
In this paper, we present a new fourth-order iterative method for solving nonlinear equations. Per iteration the new method requires two evaluations of the function and one evaluation of its first derivative.and the efficiency index equal to 1.587. Several numerical examples are given to illustrate the efficiency and performance of some of the presented methods.
