A note on infinity norm bounds for the inverses of Nekrasov matrices
Zhenhua Lyu, Dan Liu, Shiyun Wang, Feng Gao · Mathematical Methods in the Applied Sciences · 2024
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.
