The Judgement for M-Matrices in Signal Processing
Special matrices play an important role in matrix analysis and matrix computation more and more. So it can give improvements by great progress obtained in the researches on special matrices in computational mathematics. In this paper, motivated by , we give a simple and convenient judging method which can be used to judge whether an nonnegative real matrix A is a M-matrix or not.
