Comparing pivoting strategies for almost strictly sign regular matrices 2018 Access copy available to the general public Unrestricted In this paper some properties of two-determinant pivoting for Neville elimination are presented. In particular, we consider a zero-increasing property and we show an optimal normwise growth factor. Comparisons with other pivoting strategies for Neville elimination and with Gaussian elimination with partial pivoting of almost strictly sign regular matrices are performed. Numerical examples are included. info:eu-repo/grantAgreement/ES/MICINN/MTM2015-68805-REDT info:eu-repo/grantAgreement/ES/MINECO-FEDER/MTM2015-65433-P info:eu-repo/grantAgreement/ES/MINECO-FEDER/TIN2017-87600-P info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.883 2018 MATHEMATICS, APPLIED 47 / 254 = 0.185 2018 Q1 T1 0.849 2018 Computational Mathematics 2018 Q2 Applied Mathematics 2018 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-1340-0666 Peña, J.M.
