Nonstationary multisplittings with general weighting matrices
Migallón Gomis, Violeta - Penadés Martínez, José - Szyld, Daniel B.

Formato:	info:eu-repo/semantics/article
Enlaces:	In the convergence theory of multisplittings for symmetric positive definite (s.p.d.) matrices it is usually assumed that the weighting matrices are scalar matrices, i.e., multiples of the identity. In this paper, this restrictive condition is eliminated. In its place it…
