摘要


设A,E为n×n阶矩阵,对于2个矩阵行列式之差的上界估计,通过一种新的矩阵范数改进该结论,运用Matlab进行了实例验证,结果更优. Let A and E be complex matrices. For the upper bounds of determinants, it have been proved that:we introduce a new norm, which improve the inequalities slightly. Finally, by using the mathematical software matlab calculation , we prove that the conclusion of this paper is better than the other results through a concrete example.
