摘要
研究时间分数阶常系数对流-扩散方程的数值解,提出了一种只需要存储部分历史数据的分数阶微分方程的数值计算方法,并给出了误差估计.
The numerical solution for time fractional advection-dispersion equations with invariable coefficients are considered. A new numerical method for the fractional differential equations that only stores part history data is presented, and its discretization error is estimated.
