mlx.core.fft.rfft

rfft(a: array, n: int | None = None, axis: int = -1, stream: Stream | Device | None = None) → array

對實數輸入的一維離散傅立葉轉換。

The output has the same shape as the input except along axis in which case it has size n // 2 + 1.

參數:

• a (array) -- The input array. If the array is complex it will be silently cast to a real type.

• n (int, optional) -- Size of the transformed axis. The corresponding axis in the input is truncated or padded with zeros to match n. The default value is a.shape[axis].

• axis (int, optional) -- Axis along which to perform the FFT. The default is -1.

回傳:

The DFT of the input along the given axis. The output data type will be complex.
