Numerical Computation and Stability Analysis for the Fractional Subdiffusions with Spatial Variable Coefficients
In this paper, we propose an efficient compact finite difference method for a class of time-fractional subdiffusion equations with spatially variable coefficients. Based on the L2-1σ approximation formula of the time-fractional derivative and a fourth-order compact finite difference approximation to...
