bartorch.ifft

bartorch.ifft()

Inverse Fourier transform along axes: fft() with inverse=True.

Parameters:

• input (torch.Tensor) – Array to transform.

• axes (int or tuple of int) – Axes to transform, as indices into input.shape.

• unitary (bool, default=False) – Scale by one over the square root of the transformed size; otherwise unnormalized.

• uncentred (bool, default=False) – Keep the zero frequency and the origin at index zero.

Returns:

The shape of input.

Return type:

torch.Tensor
