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#

The inverse of rfft().

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

Parameters:

  • a (array) – The input array.

  • 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".

Returns:

The real array containing the inverse of rfft().

Return type:

array
