摘要
研究了鞍点问题的结构化向后误差,在定义了范数型结构化向后误差的基础上,通过大量的计算得出鞍点问题的具体误差表达式,并通过数值例子进一步验证了该方法的正确性.该结果是对鞍点问题结构化向后误差的改进和推广.
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.
