Almost strictly sign regular rectangular matrices 2022 Access copy available to the general public Unrestricted Almost strictly sign regular matrices are sign regular matrices with a special zero pattern and whose nontrivial minors are nonzero. In this paper we provide several properties of almost strictly sign regular rectangular matrices of maximal rank and analyze their QR factorization. info:eu-repo/grantAgreement/ES/MINECO-FEDER/MTM2017-90682-REDT info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-096321-B-I00 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/ 2.4 2022 MATHEMATICS, APPLIED 45 / 267 = 0.169 2022 Q1 T1 0.797 2022 Computational Mathematics 2022 Q2 Applied Mathematics 2022 Q2 5.4 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Peña, J.M.
