In this paper we provide several properties of almost strictly sign regular rectangular matrices of maximal rank and analyze their QR factorization.2022http://zaguan.unizar.es/record/10732210.1016/j.cam.2020.113121http://zaguan.unizar.es/record/107322oai:zaguan.unizar.es:107322info:eu-repo/grantAgreement/ES/MINECO-FEDER/MTM2017-90682-REDTinfo:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-096321-B-I00info:eu-repo/grantAgreement/ES/MINECO-FEDER/TIN2017-87600-PJournal of Computational and Applied Mathematics 404 (2022), 113121by-nc-ndhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/info:eu-repo/semantics/openAccess
