摘要
通过利用弱链对角占优M-矩阵的逆矩阵的无穷大范数的范围,结合不等式的放缩技巧,给出弱链对角占优B-矩阵线性互补问题解的误差界新估计式.理论分析和数值算例均证明新的估计式改进了近期一些已有的结果.
By using the infinite norm range of the inverse matrix of the weakly diagonally dominant M-matrix,combined with the expansion and contraction techniques of the inequality,a new error bound estimator for the linear complementarity problem of weakly diagonally dominant B-matrix is given.Both theoretical analysis arid numerical examples show that the new estimator improves some existing results.
