摘　　要：在研究Nekrasov矩阵A的逆矩阵无穷范数上界的基础上,利用严格对角占优矩阵经典的线性互补误差界估计式,得到了Nekrasov矩阵A的线性互补问题的误差界,并借助数值算例对估计式的优越性进行了说明.On the basis of studying the upper bound of the infinite norm of the inverse matrix of Nekrasov A,the error bounds for linear complementarity of A is obtained by using the classical linear complementary error bound estimation formula of diagonally dominant matrices.At the same time,the superiority of the estimation formula is illustrated by numerical examples.
