Sufficient conditions to assure that these matrices are either totally positive or inverse of totally positive matrices are provided. In these cases, the presented method can be used to compute their eigenvalues, singular values and inverses with high relative accuracy. Numerical examples illustrate the high accuracy of our approach.2025http://zaguan.unizar.es/record/15066810.3390/math13020303http://zaguan.unizar.es/record/150668oai:zaguan.unizar.es:150668info:eu-repo/grantAgreement/ES/DGA/E41-23Rinfo:eu-repo/grantAgreement/ES/MCIU/PID2022-138569NB-I00info:eu-repo/grantAgreement/ES/MCIU/RED2022-134176-TMathematics 13, 2 (2025), 303 [14 pp.]byhttps://creativecommons.org/licenses/by/4.0/deed.esinfo:eu-repo/semantics/openAccess
