基于求解常微分方程刚性问题的A-稳定Rosenbrock方法,引入一类求解非线性方程的半隐式迭代法,给出了收敛阶的分析.通过几个困难的方程求解问题,与Newton法、光滑与阻尼方法进行了数值比较。
Based on the A-stable Rosenbrock methods for solving stiff problem of ordinary differential equation, a class of semi-implicit iterative methods for solving nonlinear equations is presented. The convergence orders of the methods are given. Comparisons of computational results are made with New- ton' s method and smoothing or damping techniques on several difficult problems.
