a: The input array.s: Sizes of the transformed axes. The corresponding axes in the input are truncated or padded with zeros to match the sizes ins. The default value is the sizes ofaalongaxesif not specified.axes: Axes along which to perform the FFT. The default isNonein which case the FFT is over the lastlen(s)axes are or all axes ifsis alsoNone.
