Zusammenfassung --AbstractVerbesserte Einzelschrittverfahren. Ausgehend von der Theorie L-regul~irer Zerlegungen erhalten wir dem Einzelschrittverfahren/ihnliche Iterationsverfahren zur L6sung linearer Gleichungssysteme A x = bmit einer M-Matrix A und vergleichen die Konvergenzgeschwindigkeiten. Im AnschluB daran werden einige der neuen Verfahren auf Matrizen mit Bandstruktur angewendet und ihre Vorztige anhand numerischer Beispiele demonstriert.Some Gauss-Seidel Like Iterative Methods. Based on the theory of L-weak-regular splittings there will be described some Gauss-Seidel like iterative methods to solve systems of linear equations A x = b with an M-Matrix A. Then we compare their rapidity of convergence, apply them especially to tridiagonal M-matrices and give some numerical examples.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
