Args: target (int): The size of input array. real (bool): ``True`` if the FFT involves real input or output. This parameter is of no use, and only for compatibility to SciPy's interface. Returns: int: The smallest fast length greater than or equal to the input value. .. seealso:: :func:`scipy.fft.next_fast_len` .. note:: It may return a different value to :func:`scipy.fft.next_fast_len` as pocketfft's prime factors are different from cuFFT's factors.
