make_subsampled_grid

hcipy.field.make_subsampled_grid(grid, undersampling)

Make a new grid that undersamples by a factor undersampling.

Note

The dimensions of the grid must be divisible by undersampling.

Parameters:

gridGrid

The grid that we want to oversample.

undersamplinginteger or scalar or ndarray

The factor by which to undersample. If this is a scalar, it will be rounded to the nearest integer. If this is an array, a different undersampling factor will be used for each dimension.

Returns:

Grid

The undersampled grid.
