本文研究了非线性方程求根问题.利用权函数方法,获得了一种三步8阶收敛的史蒂芬森型方法.实验结果表明本文提出的方法计算时间少于其它同阶的最优方法.
In this paper, we present a family of three-step eighth-order Steffensen type meth- ods for solving nonlinear equations by using weight function methods. Numerical experiments show that these methods require less time to converge than the other optimal methods.
