A CMV--based eigensolver for companion matrices
Roberto Bevilacqua, Gianna M. Del Corso, Luca gemignani
In this paper we present a novel matrix method for polynomial rootfinding. By exploiting the properties of the QR eigenvalue algorithm applied to a suitable CMV-like form of a comp…
Exponential Splines and Pseudo-Splines: Generation versus reproduction of exponential polynomials
Costanza Conti, Luca Gemignani, Lucia Romani
Subdivision schemes are iterative methods for the design of smooth curves and surfaces. Any linear subdivision scheme can be identified by a sequence of Laurent polynomials, also c…
Implicit QR for Companion-like Pencils
Paola Boito, Yuli Eidelman, Luca Gemignani
A fast implicit QR algorithm for eigenvalue computation of low rank corrections of unitary matrices is adjusted to work with matrix pencils arising from polynomial zerofinding prob…
