摘要
本文对改进的牛顿迭代法做了进一步的研究.论文给出了这种新的迭代技术的动力系统行为和收敛性分析.同时也描述了这类迭代法及其离散形式的优越性.与经典的牛顿迭代法相比较,论文的数值实验验证了所得的理论分析结果.
In this paper, we present a new insight into an improvement on Newton's iterative method proposed by Wu (2000). We pursue our further study on the dynamic behaviour and convergence analysis for the new Newton-type method, and present the superiority analysis for the improved iterative method and its discrete versions. Numerical examples confirm our theoretical analysis in comparison with classical Newton-type methods.
