摘要
对解非线性方程组Newton迭代格式进行了改进,得到了两种比Newton法较为宽松的并且收敛速度较快的新的迭代格式,从而构造了两种新的Newton型迭代法,理论分析和数值实验证明这两种方法是稳定且有效的。
We improve Newton's iteration method of solution nonlinear equations and obtain two new loosely iteration form whose convergence rate is quicker than the Newton's iterative methods. Thus, we get two new Newton-type iterative method. The theory analysis and the numerical experiments show the above methods are stable and effective.
