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].
