Abstract :
The purpose of the letter is to develop a direct method for deriving a kth-order Routh approximant, the main advantage being that, in order to find the parameters of a kth-order approximant, it will no longer be necessary to previously obtain those of all pth-order approximants (p¿k¿1), as occurs with the Hutton and Friedland method (1975).
