Comments ''Rapid evaluation of integer-order Bessel functions using an FFT algorithm'' (and reply)

The commenter disagrees with a statement by J. Nachamkin and D.C. Hoffman (see ibid., vol.33, no.6, p.33-5, Dec. 1991) that complicated procedures are needed to find the initial terms in the recursion relation when backward-recursion techniques are used, and points out that the initial terms required to start backward recursion need not be calculated at J. Nachamkin agrees that in many cases using recursions is better than all the other methods.<
