nabu.processing.fftshift

source module nabu.processing.fftshift

Classes

• FFTshiftBase — Parameters

  ---

  shape: tuple Array shape - can be 1D or 2D. 3D is not supported. dtype: str or numpy.dtype Data type, eg. "f", numpy.complex64, ... dst_dtype: str or numpy.dtype Output data type. If not provided (default), the shift is done in-place. axes: tuple, optional Axes over which to shift. Default is None, which shifts all axes.

• OpenCLFFTshift — Parameters

  shape: tuple Array shape - can be 1D or 2D. 3D is not supported. dtype: str or numpy.dtype Data type, eg. "f", numpy.complex64, ... dst_dtype: str or numpy.dtype Output data type. If not provided (default), the shift is done in-place. axes: tuple, optional Axes over which to shift. Default is None, which shifts all axes.
