WebBluestein's algorithm can also be used to compute a more general transform based on the (unilateral) z-transform (Rabiner et al., 1969). In particular, it can compute any transform of the form: X k = ∑ n = 0 N − 1 x n z n k k = 0, …, M − 1, for an arbitrary complex number z and for differing numbers N and M of inputs and outputs.

WebSep 1, 1991 · Since it is usually possible to select a composite N, Bluestein's FFT did not receive much attention. Nevertheless because of its minimal communication requirements, the Bluestein FFT may be the algorithm of choice on multiprocessors, particularly those with the hypercube architecture. WebFor poorly factorizable sizes, scipy.fft uses Bluestein’s algorithm and so is never worse than O(n log n). Further performance improvements may be seen by zero-padding the input using next_fast_len. If x is a 1d array, then the fft is equivalent to. y [k] = np. sum (x * np. exp (-2 j * np. pi * k * np. arange (n) / n))
