    Combined matrices and conditioning 
    Bru García, Rafael; Gasso Matoses, María Teresa; Santana-De Asis, Máximo De Jesús (Elsevier, 2022-01-01)
    [EN] In this work, we study a lower bound of the condition number of a matrix by its combined matrix. In particular, we construct a special combined matrix in such a way that the sums of its columns are lower bounds of the ...

    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. ...

    Diagonal entries of the combined matrix of a totally negative matrix 
    Bru García, Rafael; Gasso Matoses, María Teresa; Gimenez Manglano, María Isabel; Santana-De Asis, Máximo De Jesús (Taylor & Francis, 2017)
    [EN] The combined matrix of a nonsingular matrix A is the Hadamard (entrywise) product . This paper deals with the characterization of the diagonal entries of a combined matrix C(A) of a given nonsingular real matrix A. A ...

    Diagonal entries of the combined matrix of sign regular matrices of arder three 
    Gasso Matoses, María Teresa; Gil, Ivan; Gimenez Manglano, María Isabel; Santana-De Asis, Máximo De Jesús; Segura, Elaine (Universidad Católica del Norte, 2021-01)
    [EN] The study of the diagonal entries of the combined matrix of a nonsingular matrix A has been considered by different authors for the classes of Mmatrices, positive definite matrices and totally positive (negative) ...

    MATRICES COMBINADAS DE ALGUNOS TIPOS DE MATRICES 
    Santana de Asís, Máximo de Jesús (Universitat Politècnica de València, 2015-04-14)
    [EN] Several authors have studied the Hadamard product or entry wise product of two matrices with di erent objectives. In particular, the product of a Hadamard matrix and the transpose of its inverse has proved useful in ...
