对简单迭代法的几点改进

Several Improvement on Simple Iterative Method

简介简单迭代法,提出了3种新的求根迭代公式.通过Matlab编写程序对算例求根,得出用这3种迭代公式求解非线性方程根的收敛速度比简单迭代法快很多.此方法是计算非线性方程根比较有效的方法,具有一定的理论价值和应用价值.

Based on simple iterative method, this paper put forward to three new iteration formulas for root. With the help of Matlab program, it was proved that the employment of three new iteration formulas for root, compared with simple iterative method. The method was an effective way of calculating the root of nonlinear equations. It had certain theoretical and practical value.
