Fast solvers for two-dimensional fractional diffusion equations using rank structured matrices

Stefano Massei, Mariarosa Mazza, Leonardo Robol

We consider the discretization of time-space diffusion equations with fractional derivatives in space and either 1D or 2D spatial domains. The use of implicit Euler scheme in time…

Quasi-Toeplitz matrix arithmetic: a MATLAB toolbox

Dario A. Bini, Stefano Massei, Leonardo Robol

A Quasi Toeplitz (QT) matrix is a semi-infinite matrix of the kind $A = T (a) + E$ where $T (a) = (a_{j - i})_{i, j \in Z^{+}}$ , $E = (e_{i, j})_{i, j \in Z^{+}}$ is compact and the norms…
