摘要
将二元非线性方程组的牛顿法作进一步推广,提出了一种新的具有几何基础的改进方法-离散牛顿法。并将二元非线性方程组的牛顿法表示成了结构形式简明、便捷的基本迭代形式-固定点迭代。
In this paper, Newton method for nonlinear equations in two unknowns is extended to a new ＆ improved method that has geometrical basis - discrete Newton method. Newton iteration method for nonlinear equations in two unknowns has also been expressed as a basic iteration form with simplified ideological structure and convenient form which is called fixed-point iteration.
