Modified DTS Iteration Methods for Spatial Fractional Diffusion Equations
For the discretized linear systems of the spatial fractional diffusion equations, we construct a class of a modified DTS iteration method and give its asymptotic convergence conditions. Then, we design a fast modified DTS preconditioner by replacing Toeplitz matrix <inline-formula><math xml...
