刚性方程的一个算法

AN ALGORITHM FOR STIFF DIFFERENTIAL EQUATION

在文献[3]中构造了一个与二阶Gear方法等价的差分格式,并采用简单迭代求解。本文详细论述了差分格式在实际计算中应采取的若干措施及程序框图,最后给出了数值例子。

A difference scheme was constructed in [3], which was equivalent to the second order Gear's method, and was solved by the simple iteration method. In this paper a practical technique for computation and a flow chart are given. Finally, we give a numerical example.
