A study of the performance of Neville elimination using two kinds of partitioning techniques [PDF]

Linear Algebra and Its Applications, 2001
In this paper, a method to compute the solution of a system of linear equations by means of Neville elimination is described using two kinds of partitioning techniques: Block and Block-striped.

A PLU-factorization of rectangular matrices by the Neville elimination [PDF]

Linear Algebra and Its Applications, 2002
In this paper we prove that Neville elimination can be matricially described by elementary matrices. A PLU-factorization is obtained for any n×m matrix, where P is a permutation matrix, L is a lower triangular matrix (product of bidiagonal factors) and U

Almost strictly sign regular matrices and Neville elimination with two-determinant pivoting [PDF]

Applied Mathematics and Computation, 2016
In 2007 Cortés and Peña introduced a pivoting strategy for the Neville elimination of nonsingular sign regular matrices and called it two-determinant pivoting.

Sign regular matrices and Neville elimination [PDF]

Linear Algebra and Its Applications, 2007
A pivoting strategy of O(n) operations for the Neville elimination of n×n nonsingular sign regular matrices is introduced. Among other nice properties, it is proved that it preserves sign regularity.

A matricial description of Neville elimination with applications to total positivity [PDF]

Linear Algebra and Its Applications, 1994
The Neville elimination process, used by the authors in some previous papers in connection with totally positive matrices, is studied in detail in the case of nonsingular matrices.
