New Localization Set of the Real Eigenvalues of Real Matrices
According to the properties of DZ type B-matrix,combining with the non-singularity of matrix and the scaling technology of inequalities,we give a new class of nonsingular matrix,namely DZ type (B)-matrix.Based on this,we give a new localization set of real eigenvalues of real matrices.Theoretical analysis and numerical examples show that the new localization set is better than the results of the existing literature.
