A Hadamard product involving inverse-positive matrices

Gasso Matoses, María Teresa; Torregrosa Sánchez, Juan Ramón; Abad Rodríguez, Manuel Francisco (De Gruyter Open, 2015-08-05)

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 ...

Combined matrices of sign regular matrices

Bru García, Rafael; Gasso Matoses, María Teresa; Gimenez Manglano, María Isabel; Santana-De Asis, Máximo De Jesús (Elsevier, 2016-06-01)

The combined matrix of a nonsingular matrix A is the Hadamard (entry wise) product C(A) = A ◦ (A−1)T . Since each row and column sum of C(A) is equal to one, the combined matrix is doubly stochastic when it is nonnegative. ...
