微分方程初值问题的求解一直是人们所关注的热点问题,本文针对微分方程初值问题的线性多步法,利用它们的局部截断误差的主项系数的某种组合对它们进行修正,提出了预测—校正算法,并给出了几种常用的预测—校正算法。 The solution to the initial value problem of differential equation has always been a hot topic of concern. In this paper, aiming at the linear multi-step method of the initial value problem of differential equations, we modify them by some combination of the main coefficient of the local truncation error Prediction - correction algorithm, and gives several commonly used prediction - correction algorithm.
