Diagonal entries of the combined matrix of sign regular matrices of order three

Abstract 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 M-matrices, positive definite matrices and totally positive (negative) matrices. This problem appears to be difficult as the results have been done...
