sigpy.linop.FFT

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

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)

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

Methods

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

Attributes

H	Return adjoint linear operator.
N	Return normal linear operator.
