Bounds for the Spectral Radius of Block H-matrices

Wei Zhang and Zheng-Zhi Han

Simple upper bounds for the spectral radius of an
H-matrix and a block H-matrix are presented. They 
represent an improvement over the bounds in [T.Z. Huang, 
R.S. Ran, A simple estimation for the spectral radius 
of (block) H-matrices, Journal of Computational Applied 
Mathematics, 177 (2005), pp. 455-459].
