"TīmeklisEZFFTF does NOT have the same limitations on N, but can take significantly longer to compute the transform (see below). The efficiency of the EZFFTF algorithm is highly dependent on the magnitude of the prime factors of N. For small prime factors, this routine is comparable in performance to the REALFT algorithm. However, for large … " - Ezfftf
