Iteration Methods for Linear Systems with Positive Definite Matrix

Abstract: Two classical first order iteration methods, Richardson iteration and HSS iteration for linear systems with positive definite matrix, are demonstrated. Theoretical analyses and computational resultsshow that the HSS iteration has the advantages of fast convergence speed, high computation efficiency,and without requirement of symmetry.
Keywords: iteration method, Richardson iteration, HSS iteration, symmetric positive definite, generalized positive definite
