利用差分算法计算分数阶FHN方程和狄利克雷(Dirichlet)零边界条件： ， 其中，数值仿真过程中需要对参数、和、进行选取。区域离散在空间方向取为个点，时间方向的步长为， 截止时间为T=1000。 2.程序 FHN_CG 是采用共轭梯度法求解线性代数方程组 Au=b。 程序 FHN_MG 是采用多重网格算法求解线性代数方程组Au=b(Using the difference algorithm to calculate the fractional FHN equation,The fractional FHN equation and the de Lickley (Dirichlet) zero boundary condition are calculated by the difference algorithm.In the process of numerical simulation, we need to select parameters, sum, and. The area discreteness is taken as a point in the direction of space, and the time step is T_1000.The 2. program FHN_CG uses the conjugate gradient method to solve the linear algebraic equation group Au_b.Program FHN_MG is a multi grid algorithm for solving linear algebraic equation group Au_b)
