Perturbation theory of transfer function matrices

V Noferini, L Nyman, J Pérez, MC Quintana - SIAM Journal on Matrix Analysis …, 2023 - SIAM
Zeros of rational transfer function matrices \(R(\lambda )\) are the eigenvalues of associated
polynomial system matrices \(P(\lambda )\) under minimality conditions. In this paper, we …

A Riemannian optimization method to compute the nearest singular pencil

FM Dopico, V Noferini, L Nyman - SIAM Journal on Matrix Analysis and …, 2024 - SIAM
Given a square pencil \(A+ \lambda B\) , where \(A\) and \(B\) are \(n\times n\) complex (resp.,
real) matrices, we consider the problem of finding the singular complex (resp., real) pencil …

Riemann-Oracle: A general-purpose Riemannian optimizer to solve nearness problems in matrix theory

M Gnazzo, V Noferini, L Nyman, F Poloni - arXiv preprint arXiv:2407.03957, 2024 - arxiv.org
We propose an extremely versatile approach to address a large family of matrix nearness
problems, possibly with additional linear constraints. Our method is based on splitting a matrix …
