摘要
首先将常用类型的模糊矩阵都纳入到了二阶占优模糊矩阵的统一框架之内,然后利用模糊矩阵的有向伴随图,指出了强连通布尔矩阵振荡的一个充要条件,依次证明了强连通的二阶占优布尔矩阵的振荡指数为2n-2,非强连通的二阶占优布尔矩阵的振荡指数为3n-4.
Almost all the fuzzy matrices of commonly used types are put into the uniform frame of 2-dominating fuzzy matrices, and then this paper gives a detailed study on the oscillate condition and oscillate index of Boolean matrices by means of directed graph of fuzzy matrix.
