Aim To study the conditions of deciding matrices with nonzero element chains as H-matrices.Methods Logical reasoning is used to prove the aforesaid conditions.Results The conditions which are used to decide the matrices containing nonzero element chains to be H-matrices are obtained.Conclusion The result plays a leading role in the theoretical studies of the control of system stability,the distribution of eigenvalue,the iterative solution of linear equations.
