Abstract
In this paper, we present several new upper bounds for the infinity norm of the inverse of Nekrasov matrices by using scaling matrices with two values on their diagonals, which improve the corresponding results of Gao et al. and Kolotilina. Numerical examples and comparisons with the existing bounds are included.
