A Fast Analysis-Based Discrete Hankel Transform Using Asymptotic Expansions
A fast and numerically stable algorithm is described for computing the discrete Hankel transform of order 0 as well as evaluating Schlömilch and Fourier--Bessel expansions in O(N(log N)[superscript 2]/loglog N) operations. The algorithm is based on an asymptotic expansion for Bessel functions of lar...
