A nonparameter criterion for generalized diagonally dominant matrices
Lei Li, Hiroshi Niki, Morito Sasanabe · International Journal of Computer Mathematics · 1999
Recently, some iterative methods have been proposed for distinguishing generalized diagonally dominant matrices. But these methods need to introduce a parameter ∊, it seems hard to decide the best value of ∊. In this paper, we discuss the iterative method showed in [5, 6] with case ∊ = 0,. prove the convergence of this method, and confirm this method is effective for distinguishing generalized diagonally dominant matrices by some examples
