摘要
给出了一个求解常微分方程初值问题y'=f(x,y),y(x0)=y0的改进的四阶方法,不用迭代,而是利用非迭代的修正的方法,使之校正1次就能达到预期的精度,弥补了不进行迭代带来的损失误差。
In this paper, the fourth order single step rule was put out for solving the initial val-ue problem: y' = f(x, y ), y (x0) =Y0 on ordinary differential equations by using revisorymethod other than iterative method while the expected precision could be attained by using onlyone revision, so that the lost error caused by not using iterative method were remedied.
