Robust stability of cellular neural networks with delay: linear matrix inequality approach: reply (comment)

Dr Zhou´s observation that the proof as given in the work of Singh is valid only for non-singular A^taumacr is correct and noteworthy. It appears, however, that there are a number of ways to show that (24) implies the global asymptotic stability of the origin of (12) even if A^taumacr is singular. One way, as the author shows, emerges from Singh itself.
