mrinufft.trajectories.sampling.create_polynomial_density(shape, decay, resolution=None)[source]#

Create a density with polynomial decay from the center.

Parameters:
  • shape (tuple of int) – The shape of the density grid.

  • decay (float) – The exponent that controls the rate of decay for density.

  • resolution (np.ndarray, optional) – Resolution scaling factors for each dimension of the density grid, by default None.

Returns:

A density array with polynomial decay.

Return type:

np.ndarray
