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. 000078123 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/MTM2015-68805-REDT$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/MTM2015-65433-P$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/TIN2017-87600-P 000078123 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000078123 590__ $$a1.883$$b2018 000078123 591__ $$aMATHEMATICS, APPLIED$$b47 / 254 = 0.185$$c2018$$dQ1$$eT1 000078123 592__ $$a0.849$$b2018 000078123 593__ $$aComputational Mathematics$$c2018$$dQ2 000078123 593__ $$aApplied Mathematics$$c2018$$dQ2 000078123 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000078123 700__ $$0(orcid)0000-0002-1340-0666$$aPeña, J.M.$$uUniversidad de Zaragoza 000078123 700__ $$aSerrano, M.L. 000078123 7102_ $$12005$$2595$$aUniversidad de Zaragoza$$bDpto.
