摘要
给出了求解一维波动方程的显式有限差分外推法,证明了该方法是四阶方法.通过三个数值算例,验证了该方法的精确性和有效性.
Based on the extrapolation principle and explicit finite difference scheme of one dimensional wave equation, an accelerated method is formed and proved to be fourth-order. The effectiveness and accuracy of this method are verified through three numerical examples.
