一个求解非线性方程的迭代方法

An Iterative Method of Making a Solution of Nonlinear Equation

本文给出了解非线性方程 f(x)=0在区间[a,b]上求单根的一个迭代法,只要求函数y=f(x)在[a,b]上连续,因而有广泛的适用性,是方程求解行之有效的方法。

In the paper,an iterative method is given of extracting a simple root to solve nonlinear eguation f(x)=0 in region(a,b).The function y=f(x)is required to be continuous in region(a,b),so the method has extensive applicability and serves as an effective one for the solution of equation.
