摘要
最近,在一些文章中(参看[1][2][3])研究了M-阵与奇异M-阵的分解问题。然而这些文章都没有讨论分解式的唯一性。本文主要讨论M-阵与奇异M-阵分解的唯一性问题,并得到相应的结果(即定理1-6)。
Recently, some authors in their papers (see[1] [2] [3]) have studiedthe factorizations of M-matrices and singular M-matrices. However in thesepapers the uniqueness of factorization was not discussed. The purpose of thispaper is to discuss the uniqueness of factorization for M-matrices and singu-lar M-matrices and some conclusions have been obtained (i. e. Theorems1-6).
