Row completion of polynomial and rational matrices II
Agurtzane Amparan, Itziar Baragaña, Silvia Marcaida +1
We study the row completion problem of polynomial and rational matrices with partial prescription of the structural data. The prescription of the complete structural data has been…
Row completion of polynomial and rational matrices
Agurtzane Amparan, Itziar Baragaña, Silvia Marcaida +1
We characterize the existence of a polynomial (rational) matrix when its eigenstructure (complete structural data) and some of its rows are prescribed. For polynomial matrices, thi…
Weierstrass structure and eigenvalue placement of regular matrix pencils under low rank perturbations
Itziar Baragaña, Alicia Roca
We solve the problem of determining the Weierstrass structure of a regular matrix pencil obtained by a low rank perturbation of another regular matrix pencil. We apply the result t…
