Abstract :
The commenter shows that the algorithm presented in the above paper (ibid., vol.ASSP-35, no.10, p.1484-5, Oct. 1987) requires exactly the same number of multiplications as, but more additions than, prevalent methods for the computation of the DHT (discrete Hartley transform) by existing methods, contrary to the author´s claim.<>
