摘要
利用弱链对角占优M-矩阵的逆矩阵的无穷大范数的范围,给出了弱链对角占优B-矩阵线性互补问题误差界新的估计式.理论证明及数值算例均表明所得估计改进了某些现有结果.
Based on the range for the infinity norm of inverse matrices of weakly chained diag- onMly dominant M-matrices, some new error bounds for the linear complementarity problem are obtained when the involved matrices are weakly chained diagonally dominant B-matrices. Numerical examples are given to show that the new bounds are better than some existing results.
