mlx.core.fft.irfft

irfft(a: array, n: int | None = None, axis: int = -1, norm: str = 'backward', stream: Stream | mlx.core.ThreadLocalStream | Device | None = None) → array

rfft() 的反運算。

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

參數:

• a (array) -- 輸入陣列。

• n (int, optional) -- Size of the transformed axis. The corresponding axis in the input is truncated or padded with zeros to match n // 2 + 1. The default value is a.shape[axis] // 2 + 1.

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

• norm (str, optional) -- One of "backward", "ortho", or "forward". Default is "backward".

回傳值:
