摘要
根据P-矩阵的子类B-矩阵的定义和性质,利用严格对角占优M-矩阵的逆的无穷大范数的上界估计式和不等式的放缩技巧,得到了B-矩阵线性互补问题解的误差界新估计式.理论分析和数值例子说明,新估计式改进了现有文献的相关结果.
According to the definition and properties of the subclass of P-matrices B-matrices,a new estimate of the error bounds for the linear complementarity problem of B-matrices is obtained by using the upper bound estimation of the inverse infinite norm of a strictly diagonally dominant M-matrices and the scaling technique of inequality.Theoretical analysis and numerical examples show that the new estimate improves the relevant results in the existing literature.
