A Hadamard Product Involving Inverse-Positive Matrices
SPECIAL MATRICES(2015)
摘要
In this paper we study the Hadamard product of inverse-positive matrices. We observe that this class of matrices is not closed under the Hadamard product, but we show that for a particular sign pattern of the inverse-positive matrices A and B, the Hadamard product A omicron B-1 is again an inverse-positive matrix.
