摘要
本文以代数插值为工具,构造了两类具良好收缩性质的解STIFF常微分方程初值问题的混合方法,数值试验表明,它们的精度优于Gear方法,由于其不等距步长公式极易求得,变阶变步长实现成为可能。
In this paper we use algebraic interpolation, construct two classes of methods for integrating initial value problem of O.D.Es, which have good contrativity. Numerical results indicate that they are more accurate than Gear's methods. The variable step methods are easy obtained, thus variable-step variable-order implemetation becomes possible.
