摘要
将解非线性方程组转化为解常微分方程组的初值问题,用常微分方程数值解法,以变步长的方式求其解。文中提出两个变步长的算法,给出一些数值例子,说明算法性能良好,并对算法的效率进行分析。
The solution of nonlinear equations can be transformed into that of initial-value problems of ordinary differential equations.The paper presents two variable step-size algorithms to solve the transformed ODE problems.Numerical examples are given.The results show that the given algorithms have good performance.Moreover,their efficiencies are analyzed.
