sigpy.linop.FFT

class sigpy.linop.FFT(shape, axes=None, center=True)[source]

FFT linear operator.

Parameters:
  • ishape (tuple of int) – Input shape
  • axes (None or tuple of int) – Axes to perform FFT. If None, applies on all axes.
  • center (bool) – Toggle center FFT.
__init__(shape, axes=None, center=True)[source]

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(shape[, axes, center]) Initialize self.
apply(input) Apply linear operation on input.
