| dc.description.abstract | Neste traballo abordarase a aplicación de métodos numéricos para o cálculo dos autovalores dunha matriz desde a descripción, análise, codificación e execución en exemplos académicos. Inicialmente, realizarase unha introdución que explica a importancia do cálculo de autovalores na vida cotiá, seguido dunha clasificación dos distintos métodos dispoñibles (Capítulo 1). A continuación, o estudo centrarase na análise teórica e computacional dos métodos descritos. No Capítulo 2 estúdase o método de Householder para a redución dunha matriz calquera a unha semellante de tipo Hessenberg superior, así como a súa adaptación ao caso dunha matriz simétrica (que se reduce a unha tridiagonal simétrica). O Capítulo 3 está dedicado ao método de Hyman para o cálculo dos autovalores dunha matriz Hessenberg superior resolvendo o seu polinomio característico usando Newton-Raphson. Finalmente, no Capítulo 4 estúdase e prográmase o método de bisección de Givens para calcular as raíces do polinomio característico utilizando as propiedades dunha sucesión de Sturm. | |
| dc.description.abstract | This work will address the application of numerical methods for the calculation of eigenvalues of a matrix, from the description, analysis, coding, and execution in academic examples. Initially, an introduction will be provided explaining the importance of eigenvalue calculation in daily life, followed by a classification of the different available methods (Chapter 1). Next, the study will focus on the theoretical and computational analysis of the methods described. Chapter 2 examines the Householder method for reducing any matrix to a similar upper Hessenberg type, as well as its adaptation to the case of a symmetric matrix (which is reduced to a symmetric tridiagonal matrix). Chapter 3 is dedicated to the Hyman method for computing the eigenvalues of an upper Hessenberg matrix by solving its characteristic polynomial using Newton-Raphson. Finally, in Chapter 4, the Givens bisection method is studied and programmed to calculate the roots of the characteristic polynomial using the properties of a Sturm sequence. | |
