-
摘要: 本文给出一种求解病态方程的连分式外推算法，并对算法的稳定性进行了讨论，证明在三次以内的连分式外推下，方法具有A-稳定．另外，文中给出一种处理间断问题的方法．Abstract: In this paper,we present a continued fraction extrapolation algorithm for stiffsystem simulations,and also discuss the stability of the algorithm.It is concluded thatthe algorithm is A-stable within three extrapolating orders.Finally,the paper gives amethod for dealing with discontinuity problems.
