The stability problem for delayed complex-valued recurrent neural networks is considered in this paper. By separating complex-valued neural networks into real and imaginary parts, forming an equivalent real-valued system, and constructing appropriate Lyapunov functional, a sufficient condition to ascertain the existence, uniqueness, and globally asymptotical stability of the equilibrium point of complex-valued systems is provided in terms of linear matrix inequality. Meanwhile, the errors in the recent work are pointed out, and even if the result therein is correct, it is shown that our result not only improves but also generalizes in that work. Numerical examples are given to show the effectiveness and merits of the present result.
