A note on convergence of line iterative methods for a nine-point matrix
We prove the convergence of line iterative methods for solving the linear system arising from a 9-point compact discretization of a special two dimensional convection-diiusion equation. The results provide rigorous justiication for the numerical experiments conducted elsewhere, which demonstrate the high accuracy and stability advantages of the fourth-order compact scheme.
متن کاملNote: interpreting iterative methods convergence with diffusion point of view
Based on the previous research results on the diffusion approach [1] to solve fixed point problem in linear algebra, we propose here a new analysis of the convergence speed of different iteration methods. In Section II, we define the iteration methods that are considered. Section III shows how to define the associated equivalent diffusion iteration. Section IV shows few examples to illustrate t...
متن کاملOn the modified iterative methods for $M$-matrix linear systems
This paper deals with scrutinizing the convergence properties of iterative methods to solve linear system of equations. Recently, several types of the preconditioners have been applied for ameliorating the rate of convergence of the Accelerated Overrelaxation (AOR) method. In this paper, we study the applicability of a general class of the preconditioned iterative methods under certain conditio...

the issue of curriculum and syllabus evaluation and revision has been in center of attention right from when curriculum came into attention of educational institutions. thus everywhere in the world in educational institutions curricula and syllabi are evaluated and revised based on the goals, the needs, existing content, etc.. in iran any curriculum is designed in a committee of specialists and...
A note on local and global convergence analysis of iterative aggregation-disaggregation methods
The purpose of the paper is to present some convergence properties of the iterative aggregation-disaggregation method for computing a stationary probability distribution vector of a column stochastic matrix. A sufficient condition for the local convergence property and the corresponding rate of convergence are established. Some global convergence considerations are presented. Several illustrati...
