Nonstationary Multisplittings with General Weighting Matrices
Nonstationary Multisplittings with General Weighting Matrices
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 is assumed that more than one (inner) iteration is performed …
