摘要
首先研究∑_(1)-SDD矩阵A的逆矩阵无穷范数的上界,其次,在该上界的基础上,利用∑_(1)-SDD矩阵A和=I-D+DA的关系,得到了A的线性互补问题的误差界,同时借助数值算例对估计式的优越性进行了说明.最后,得到了B-∑_(1)-SDD矩阵线性互补问题的误差界.
First,the upper bound of the infinite norm of the inverse matrix∑_(1)-SDD of A has been studied,Secondly,on the basis of the upper boundary,using the relation∑_(1)-SDD matrix of A and=I-D+DA,the error bounds for linear complementarity of A is obtained.At the same time,numerical examples are used to illustrate the superiority of the estimator.Lastly,Further obtained the error bounds for linear complementarity of B-∑_(1)-SDD matrix.
