Concepts inAlgorithm 588: Fast Hankel Transforms Using Related and Lagged Convolutions
In mathematics, the Hankel transform expresses any given function f(r) as the weighted sum of an infinite number of Bessel functions of the first kind J¿(kr). The Bessel functions in the sum are all of the same order ¿, but differ in a scaling factor k along the r-axis. The necessary coefficient F¿ of each Bessel function in the sum, as a function of the scaling factor k constitutes the transformed function.
