Fast Hessenberg reduction of some rank structured matrices
Luca Gemignani, Leonardo Robol
We develop two fast algorithms for Hessenberg reduction of a structured matrix where is a real or unitary diagonal matrix and $U, V \in\mathbb{C}^{n…

Efficient Solution of Parameter Dependent Quasiseparable Systems and Computation of Meromorphic Matrix Functions
Paola Boito, Yuli Eidelman, Luca Gemignani
In this paper we focus on the solution of shifted quasiseparable systems and of more general parameter dependent matrix equations with quasiseparable representations. We propose an…

A Real QZ Algorithm for Structured Companion Pencils
Paola Boito, Yuli Eidelman, Luca Gemignani
We design a fast implicit real QZ algorithm for eigenvalue computation of structured companion pencils arising from linearizations of polynomial rootfinding problems. The modified…
