ifftn(a: array, s: tuple[int, ...] | None = None, axes: Sequence[int] | None = None, stream: Stream | Device | None = None) → array

$n$ 維離散傅立葉反轉換。

參數:

• a (array) -- The input array.

• s (list(int), optional) -- Sizes of the transformed axes. The corresponding axes in the input are truncated or padded with zeros to match the sizes in s. The default value is the sizes of a along axes.

• axes (list(int), optional) -- Axes along which to perform the FFT. The default is None in which case the FFT is over the last len(s) axes or all axes if s is also None.

回傳:

The inverse DFT of the input along the given axes.
