Application of Laguerre matrix polynomials to the numerical inversion of Laplace transforms of matrix functions

Sastre, Jorge; Defez Candel, Emilio; Jódar Sánchez, Lucas Antonio (Elsevier, 2011-09)

This paper presents an application of Laguerre matrix polynomial series to the numerical inversion of Laplace transforms of matrix functions. © 2011 Elsevier Ltd. All rights reserved.
Characterizations of {K,s+1}-Potent Matrices and Applications

Lebtahi Ep-Kadi-Hahifi, Leila; Romero Martínez, José Oscar; Thome, Néstor (Elsevier, 2012-01-15)

Recently, situations where a matrix coincides with some of its powers have been studied. This kind of matrices is related to the generalized inverse matrices. On the other hand, it is possible to introduce another class ...
Desarrollo e implementación de una aplicación informática con Matlab para la encriptación fractal del imágenes basadas en el Cifrado de Hill

Viguer Güémez, Albert (Universitat Politècnica de València, 2020-11-13)

[ES] En este trabajo final de grado se presenta una novedosa aplicación del álgebra matricial y la aritmética modular al proceso de encriptación de imágenes, a partir de los procesos iterativos en el plano complejo que dan ...
Fast exact variable order affine projection algorithm

Ferrer Contreras, Miguel; Gonzalez, Alberto; Diego Antón, María de; Piñero Sipán, María Gemma (Elsevier, 2012-09)

Variable order affine projection algorithms have been recently presented to be used when not only the convergence speed of the algorithm has to be adjusted but also its computational cost and its final residual error. These ...
Improvement on the bound of Hermite matrix polynomials

Defez Candel, Emilio; Tung, Michael Ming-Sha; Sastre, Jorge (Elsevier, 2011-04-15)

In this paper, we introduce an improved bound on the 2-norm of Hermite matrix polynomials. As a consequence, this estimate enables us to present and prove a matrix version of the Riemann-Lebesgue lemma for Fourier transforms. ...
Is A in Cn,n a general H-matrix?

Bru García, Rafael; Gimenez Manglano, María Isabel; Hadjidimos, Apostolos (Elsevier, 2012-01)

H-matrices play an important role in the theory and applications of Numerical Linear Algebra. So, it is very useful to know whether a given matrix A E Cn,n, usually the coefficient of a complex linear system of algebraic ...
Segmentation strategy for the efficient analysis and design of substrate integrated waveguide directly coupled cavity filters

Martínez-Zamora, Juan Ángel; Belenguer, Ángel; Esteban González, Héctor; Boria Esbert, Vicente Enrique (Institution of Engineering and Technology (IET), 2016-02-19)

In this study, a new segmentation strategy is presented for the full-wave analysis of directly coupled cavity filters in substrate integrated waveguide (SIW) technology. The whole SIW filter is enclosed inside an external ...
