A Hadamard product involving inverse-positive matrices
In this paperwe 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 ◦ B−1 is again an inverse-positive...

| Summary: | In this paperwe 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 ◦ B−1 is again an inverse-positive matrix. |
