When is a matrix unitary or Hermitian plus low rank?
Gianna M. Del Corso, Federico Poloni, Leonardo Robol +1
Hermitian and unitary matrices are two representatives of the class of normal matrices whose full eigenvalue decomposition can be stably computed in quadratic computing com plexity…
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…
Computing performability measures in Markov chains by means of matrix functions
Giulio Masetti, Leonardo Robol
We discuss the efficient computation of performance, reliability, and availability measures for Markov chains; these metrics, and the ones obtained by combining them, are often cal…
Finite element model updating for structural applications
Maria Girardi, Cristina Padovani, Daniele Pellegrini +2
A novel method for performing model updating on finite element models is presented. The approach is particularly tailored to modal analyses of buildings, by which the lowest freque…
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 where , is compact and the norms…
