Synopsis

In this talk we will introduce a new class of fast algorithms for the application of certain special function transforms to arbitrary vectors. The scheme is applicable to a number of transforms, including the Fourier–Bessel transform, the non-equispaced Fourier transform, transforms associated with all classical orthogonal polynomials, etc. The complexity of the scheme is O(n log n), and we illustrate the performance via several numerical examples.
