Band-Toeplitz preconditioners for ill-conditioned Toeplitz systems
Preconditioning for Toeplitz systems has been an active research area over the past few decades. Along this line of research, circulant preconditioners have been recently proposed for the Toeplitz-like system arising from discretizing fractional diffusion equations. A common approach is to combine a...
