Title: A Comparison Theorem in the IMGS and SOR Iterative Method
Abstract: The linear systems were solved by the iterative method.The matrix iterative analysis and matrix comparison theorems were used to compare the convergence speed in the successive over-relaxation iterative method(SOR method) and the Gauss-Seidel method of the preconditioner P=I+Cα(IMGS method),the comparison conclusion is better.And the numerical example was given.
