Abstract:
In this paper, we consider a fractional advection-diffusion equation. The implicit difference method is used to discretize the fractional diffusion equation. To improve the implicit method, we use a preconditioned generalized minimal residual (preconditioned GMRES) method. Numerical experiments are given to illustrate the efficiency of the method.
