Intensity changes of states coherence for a linear network system. (a) When the input vector \(u=0\), the coherence between the states is strong. (b) When the input vector u is the standard Gaussian noise, the coherence between the states is weakened. The thickness degree of the interconnection between nodes represents the strength or the weakness of states coherence.
