Universidad de Zaragoza (orcid)0000-0002-1101-6230 Accurate computations with matrices related to bases {tie¿t} 2022 Access copy available to the general public Unrestricted The total positivity of collocation, Wronskian and Gram matrices corresponding to bases of the form (eλt,teλt,…,tneλt) is analyzed. A bidiagonal decomposition providing the accurate numerical resolution of algebraic linear problems with these matrices is derived. The numerical experimentation confirms the accuracy of the proposed methods. 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 http://creativecommons.org/licenses/by/3.0/es/ 1.7 2022 MATHEMATICS, APPLIED 95 / 267 = 0.356 2022 Q2 T2 0.813 2022 Computational Mathematics 2022 Q2 Applied Mathematics 2022 Q2 3.4 2022 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peña, J.
