Constructing matrix geometric means
Federico Poloni
In this paper, we analyze the process of "assembling" new matrix geometric means from existing ones, through function composition or limit processes. We show that for n=4 a new mat…

A note on the O(n)-storage implementation of the GKO algorithm
Federico Poloni
We propose a new O(n)-space implementation of the GKO-Cauchy algorithm for the solution of linear systems with Cauchy-like matrix. Despite its slightly higher computational cost, t…
