Consider the linear system Ax=b where the coefficient matrix A is an M-matrix. In the present work, it is proved that the rate of convergence of the Gauss-Seidel method is faster than the mixed-type splitting and AOR (SOR) iterative methods for solving M-matrix linear systems. Furthermore, we improve the rate of convergence of the mixed-type splitting iterative method by applying a preconditio...

Introduction: This study was conducted to determine the most importantstrengths and weaknesses of the present evaluation system in Tehran University of Medical Sciences and achieve the main factors to improve this system.Method: It was a mixed method study design in two separate and sequential phases. The first phase was a qualitative step applying a document analysis method to interpret the pr...
