Abstract
In this paper,we present some lower bounds for the minimum eigenvalue ofHadamard product of an M-matrix and inverse M-matrix, by virtue of some eigenvalue inclusion sets with parameter α and inequality scaling techniques. And we analyze relationships between the sizes of the obtained lower bounds. A series of numerical examples are given to demonstrate that our results can be more accurate than the existing results by selecting an appropriate parameter α.
