fft2(a: array, s: tuple[int, ...] | None = None, axes: Sequence[int] | None = [-2, -1], stream: Stream | Device | None = None) → array

Two dimensional discrete Fourier Transform.

参数:

• 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 [-2, -1].

返回:

The DFT of the input along the given axes.

返回类型:

array
