Universidad de Zaragoza (orcid)0000-0002-1101-6230 Accurate computations with Wronskian matrices of Bessel and Laguerre polynomials 2022 Access copy available to the general public Unrestricted This paper provides an accurate method to obtain the bidiagonal factorization of Wronskian matrices of Bessel polynomials and of Laguerre polynomials. This method can be used to compute with high relative accuracy their singular values, the inverse of these matrices, as well as the solution of some related systems of linear equations. Numerical examples illustrating the theoretical results are included. © 2022 The Authors info:eu-repo/grantAgreement/ES/DGA/E41-20R info:eu-repo/grantAgreement/ES/MCIU-AEI/PGC2018-096321-B-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.1 2022 MATHEMATICS 101 / 329 = 0.307 2022 Q2 T1 MATHEMATICS, APPLIED 161 / 267 = 0.603 2022 Q3 T2 0.851 2022 Algebra and Number Theory 2022 Q1 Numerical Analysis 2022 Q1 Discrete Mathematics and Combinatorics 2022 Q1 Geometry and Topology 2022 Q2 2.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peña, J.M.
