Diagonal entries of the combined matrix of a totally negative matrix [PDF]
Linear and Multilinear Algebra, 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.
