摘要
利用S impson求积公式,提出了一种求解常微分方程初值问题的单步方法。该方法为3点4阶方法,其绝对稳定区间大于同阶的Adam s内、外插值法的绝对稳定区间。最后通过数值算例表明,该方法具有一定的优势。
With Simpson - integration, we get a class of one step method for solving initial value problems of ODE, which is 3 point 4 order method. The interval of its absolute stability is larger than that of Adams methods. Numerical tests show that the method is efficient.
