D-Z矩阵线性互补问题解的误差界的新估计

New Estimation of Error Bound for the Solution of Linear Complementary Problems for D Z Matrix

根据D-Z矩阵A的定义和元素特征,应用‖A-1‖∞的上界估计式和不等式放缩技术,给出了该类矩阵线性互补问题误差界的一个新估计式,且用算例表明了新估计式的优越性。

According to the definition of D-Zmatrix and the characteristics of the elements,a new estimation for the error bound of the linear complementarity problems is given by using the upper bound of‖A-1‖∞ and the inequality scaling technique.An example is given to show the superiority of the new estimation formula.
