sigpy.linop.NUFFTAdjoint

class sigpy.linop.NUFFTAdjoint(oshape, coord, oversamp=1.25, width=4)

NUFFT adjoint linear operator.

Parameters:

• oshape (tuple of int) – Output shape
• coord (array) – Coordinates, with values [-ishape / 2, ishape / 2]
• oversamp (float) – Oversampling factor.
• width (float) – Kernel width.

__init__(oshape, coord, oversamp=1.25, width=4)

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

Methods

__init__(oshape, coord[, oversamp, width])	Initialize self.
apply(input)	Apply linear operation on input.

Attributes

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