Structured backward errors in linearizations
Vanni Noferini, Leonardo Robol, Raf Vandebril
A standard approach to compute the roots of a univariate polynomial is to compute the eigenvalues of an associated \emph{confederate} matrix instead, such as, for instance the comp…
A computational framework for two-dimensional random walks with restarts
Dario A. Bini, Stefano Massei, Beatrice Meini +1
The treatment of two-dimensional random walks in the quarter plane leads to Markov processes which involve semi-infinite matrices having Toeplitz or block Toeplitz structure plus a…
hm-toolbox: Matlab software for HODLR and HSS matrices
Stefano Massei, Leonardo Robol, Daniel Kressner
Matrices with hierarchical low-rank structure, including HODLR and HSS matrices, constitute a versatile tool to develop fast algorithms for addressing large-scale problems. While e…
Rational Krylov for Stieltjes matrix functions: convergence and pole selection
Stefano Massei, Leonardo Robol
Evaluating the action of a matrix function on a vector, that is , is an ubiquitous task in applications. When is large, one usually relies on Krylov…
Tensor methods for the computation of MTTA in large systems of loosely interconnected components
Leonardo Robol, Giulio Masetti
We are concerned with the computation of the mean-time-to-absorption (MTTA) for a large system of loosely interconnected components, modeled as continuous time Markov chains. In pa…
Rational Krylov and ADI iteration for infinite size quasi-Toeplitz matrix equations
Leonardo Robol
We consider a class of linear matrix equations involving semi-infinite matrices which have a quasi-Toeplitz structure. These equations arise in different settings, mostly connected…
