Toeplitz-like preconditioner for linear systems from spatial fractional diffusion equations
The article deals with constructing Toeplitz-like preconditioner for linear systems arising from finite difference discretization of the spatial fractional diffusion equations. The coefficient matrices of these linear systems have an $S+L$ structure, where $S$ is a symmetric positive definite (...
