| Abstract: | Structurization backward errors for saddle point problem were discussed.After defining structuring backward errors,the expression of perturbation backward error of saddle point problem was derived with a lot of calculation,and then based on examples,the validity of the method was proved.The results of the paper are improvements and generalizations of backward errors analysis for saddle point problem. |
