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 Authors2022http://zaguan.unizar.es/record/11807110.1016/j.laa.2022.04.004http://zaguan.unizar.es/record/118071oai:zaguan.unizar.es:118071info:eu-repo/grantAgreement/ES/DGA/E41-20Rinfo:eu-repo/grantAgreement/ES/MCIU-AEI/PGC2018-096321-B-I00LINEAR ALGEBRA AND ITS APPLICATIONS 647 (2022), 31-46by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
