逆M-矩阵在Hadamard积下的封闭性
Closure Properties of Inverse M-matrices under Hadamard Product
摘要
Abstract
In the paper we prove that the class of inverse M-matrices is not closed under Had mard product, and that some important subclasses( tridiagonal inverse M-matrices, Hessenburg inverse M-matrices, and matrices whose inverse are M-matrices with unipathic digraphs) are closed under Hadamard multiplication.关键词
