摘　　要：对于数值求解常微分方程的传统方法而言,其计算量和存储量一般都是比较大的,为了解决这个问题,该文基于L2方案和一个简单的递归关系提出了一个快速高阶数值方法求解带有Caputo-Fabrizio导的分数阶微分方程,该算法在很大程度上减少了存储量和计算量,进一步的,该文分析了快速算法的可行性、误差估计和稳定性分析,并通过数值算例论证的所提方法的正确性.The computational work and storage of numerically solving the ODEs are generally huge for the traditional direct methods.To overcome this difficulty,we presents a fast high order numerical method for fractional ordinary differential equations with the Caputo-Fabrizio derivative based on a L2 scheme and a simply recurrence relation.The algorithm greatly reduces the storage capacity and the total calculation cost.Furthermore,we also analyzes the feasibility of algorithm,error estimation and stability analysis of the fast scheme.Illustrative examples are included to demonstrate the performance of our technique.
