Comparing pivoting strategies for almost strictly sign regular matrices
Alonso, P. ; Peña, J.M. (Universidad de Zaragoza) ; Serrano, M.L.
Resumen: 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.
