bartorch.fftmod

bartorch.fftmod()

Multiply by the phase that turns an uncentred transform into a centred one, along axes.

For an even size the phase is an alternating sign. BART’s fftmod.

Parameters:

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

• axes (int or tuple of int) – Axes to modulate along.

• inverse (bool, default=False) – Apply the conjugate phase.

Returns:

The shape of input.

Return type:

torch.Tensor
