Almost strictly sign regular matrices and Neville elimination with two-determinant pivoting 2016 Access copy available to the general public Unrestricted In 2007 Cortés and Peña introduced a pivoting strategy for the Neville elimination of nonsingular sign regular matrices and called it two-determinant pivoting. Neville elimination has been very useful for obtaining theoretical and practical properties for totally positive (negative) matrices and other related types of matrices. A real matrix is said to be almost strictly sign regular if all its nontrivial minors of the same order have the same strict sign. In this paper, some nice properties related with the application of Neville elimination with two-determinant pivoting strategy to almost strictly sign regular matrices are presented. info:eu-repo/grantAgreement/ES/MICINN/MTM2015-65433 info:eu-repo/grantAgreement/ES/MICINN/MTM2015-68805-REDT info:eu-repo/grantAgreement/ES/MINECO/TEC2012-38142-C04-04 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 1.738 2016 MATHEMATICS, APPLIED 35 / 255 = 0.137 2016 Q1 T1 0.943 2016 Computational Mathematics 2016 Q1 Applied Mathematics 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/submittedVersion (orcid)0000-0002-1340-0666 Peña, J.M.
