[ES] La multiplicación de matrices es una operación fundamental para la resolución de innumerables problemas matemáticos que tienen a esta operación en su base. El coste de esta operación, incluso el algoritmo utilizado, ...
[EN] This paper describes several parallel algorithmic variations of the Neville elimination. This elimination solves a system of linear equations making zeros in a matrix column by adding to each row an adequate multiple ...

Computing a matrix polynomial is the basic process in the calculation of functions of matrices by the Taylor method. One of the most efficient techniques for computing matrix polynomials is based on the Paterson– Stockmeyer ...
In this work, we developed a parallel algorithm to speed up the resolution of differential matrix Riccati
equations using a backward differentiation formula algorithm based on a fixed-point method. The role and
use of ...
