Discussion: "Analysis of a system of linear delay differential equations" ( Asl, F. M., and Ulsoy, A. G. 2003, ASME J. Dyn. Syst., Meas., Control, 125, pp. 215-223)

This work presents a commentary, of the article published by Asl and Ulsov (2003, ASME J. Dyn. Syst., Meas., Control, 125, pp. 215-223). We show by an example that their method leads to inaccurate results and is therefore erroneous.
