Comments on "An efficient algorithm for reducing transfer functions to coprime forms" [with reply]
C.-T. Chen, Charles K. Chui, G. Chen · IEEE Transactions on Automatic Control · 1988
The comments points out that the basic idea of the above mentioned paper by C.K. Chui and G. Chen (see ibid., vol.AC-32, no.6, p.521-3, June 1987) appears to be similar to one in a book written by him, and compares the two treatments. The authors reply that since all reduction formulas for rational functions are essentially based on the Euclidean algorithm, there is always similarity of some kind among them. The algorithm introduced by them has the distinction that it is a consequence of the block structure of the Pade table. They describe briefly its advantages.>
