关于模糊常矩阵的一个充分必要条件

The Necessary and sufficient Conditions for the Product of Two Fuzzy Matrices to be a Constant Fuzzy Matrix

摘要: 对模糊矩阵中一些已有的结果进行了改进,在原只有充分条件的基础上,给出了充分必要条件及其一些推论,并对模糊常矩阵的计算给出了一个完整的结果.

Abstract: Two fuzz matrices B and A, of which A is a constant fuzzy matrix,has been considered.The author has established sufficient condition for B A to be constant in previous paper.The results is improved,and the necessary and sufficient conditions are given for B A to be constant in this paper.
