(a) The simulation, where the initial value is chosen as (3,3)^𝑇, illustrates that all trajectories uniformly converge to the unique equilibrium 𝑥^∗=(2.608,5.719)^𝑇 for the ICNNs (61) with impulsive effects. (b) The simulation, where the initial value is chosen as (3,3)^𝑇, illustrates that all trajectories uniformly converge to the unique equilibrium 𝑥^∗=(2.608,5.719)^𝑇 for the ICNNs (61) without impulsive effects.
