The use of basic iterative methods for bounding a solution of a system of linear equations with an M-matrix and positive right-hand side. (English). In: Chleboun, J., Segeth, K. and Vejchodský, T. (eds.): Programs and Algorithms of Numerical Mathematics. Proceedings of Seminar. Prague, May 28-31, 2006. Institute of Mathematics AS CR, Prague, 2006. pp. 143-148
Summary:
This article presents a simple method for bounding a solution of a system of linear equations $Ax=b$ with an M-matrix and positive right-hand side [1]. Given a suitable approximation to an exact solution, the bounds are constructed by one step in a basic iterative method.
