facet_to_subgrid_2d_method_3

ska_sdp_exec_swiftly.fourier_transform_dask.facet_to_subgrid_2d_method_3(facet, distr_fft_class, base_arrays, use_dask=False)

Generate subgrid from facet 2D. 3rd Method.

Approach 3: same as 2, but starts with the vertical direction (axis=1)

and finishes with the horizontal (axis=0) axis

Parameters:

• facet – 2D numpy array of facets

• distr_fft_class – StreamingDistributedFFT class object

• base_arrays – BaseArrays class object

• use_dask – use dask.delayed or not

Returns:

approximate subgrid array (subgrids derived from facets)
