Abstract: In this paper, some new bounds for the spectral radius of iterative matrices are obtained, which generalize and improve the results in [1--6]. These results are suited to extended matrices. Numerical examples show that these new bounds are better than the earlier ones in [1--6] under same conditions.

Key words: Iterative matrix, G -function, Spectral radius, Eigenvalue
