摘要
本文给出了求解非线性方程的一种新的改进方法.利用Newton法和Heron平均,将新改进方法与其它一些迭代法作比较.数值结果表明该方法具有一定的实用价值.
In this article,we present a new modification method to solve non-linear equations. By the composition of Newton＇s method and Heron mean,we have compared this modified method with some other iterative methods,which shows that this new iterative method is robust and efficient.Numerical results show that the method has practical utility.
