Abstract:A new iterative method for solving linear equation systems is obtained.The convergence of the method is proved when the coefficient matrix is a strictly diagonally dominant matrix by rows,or irreducible weak diagonal dominant matrix by rows or symmetric positive definite matrix.Upper bound for the spectral radius of the iterative method is given.Numerical results show that the method with the proper choice of the parameter can converge rapidly.
Keywords:linear system  iterative method  convergence  algorithm
