New Upper Bounds on The Spectral Radius for the Hadamard Product of Nonnegative Matrices
Qin Zhong · Journal of Physics Conference Series · 2023
Abstract By using the eigenvalue inclusion field theorem and the commutability of the Hadamard product, new upper bound estimations of ρ (E ∘ F) are given. The new estimations can be expressed only by the elements of two nonnegative matrices, which are operable and easy to calculate. Finally, an example is given to verify that the estimation formulas in this paper are more accurate than related conclusions.
