Universidad de Zaragoza (orcid)0000-0002-1101-6230 Accurate computations with Wronskian matrices 2021 Access copy available to the general public Unrestricted In this paper we provide algorithms for computing the bidiagonal decomposition of the Wronskian matrices of the monomial basis of polynomials and of the basis of exponential polynomials. It is also shown that these algorithms can be used to perform accurately some algebraic computations with these Wronskian matrices, such as the calculation of their inverses, their eigenvalues or their singular values and the solutions of some linear systems. Numerical experiments illustrate the results. info:eu-repo/grantAgreement/ES/DGA-FEDER/Construyendo Europa desde Aragón info:eu-repo/grantAgreement/ES/DGA-FEDER/E41-17R info:eu-repo/grantAgreement/ES/MCIU-AEI/PGC2018-096321-B-I00 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.097 2021 MATHEMATICS 32 / 333 = 0.096 2021 Q1 T1 MATHEMATICS, APPLIED 71 / 267 = 0.266 2021 Q2 T1 0.96 2021 Computational Mathematics 2021 Q1 Algebra and Number Theory 2021 Q1 3.4 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Peña, J.M.
