The generalized diagonally dominant matrix (H-matrix) is a relatively activeresearch field in computational mathematics, cybernetics and matrix theory. It iswidely used in many subjects such as computational mathematics, mathemati-cal physics, economics, biology, dynamical system theory and intelligence scienceetc.. Many practical problems can be summarized to determine the H-matrix.However, it is rather difficult in practice to determine whether a matrix is anH-matrix or not. Therefore, it has great theore...
