This paper introduced a matrix of m-A matrix with the definition and use of a guide on the definition of m-matrix with the two theorems, mainly discussed the m-matrix with the determinant, rank, and home to the inverse moment A matrix with the RUF, as well as for special RUF A and B for special ties between the RUF, through some of the important proposition that found that the m-A matrix with the nature and the nature of A is very similar.
