bartorch.fft

bartorch.fft()

Fourier transform along axes, centred by default.

Parameters:

• input (torch.Tensor)

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

• inverse (bool, default=False) – Transform with the positive exponent.

• 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 at index zero rather than at n // 2.

Examples

>>> spectrum = fft(image, axes=(-2, -1), unitary=True)
