ft_utils

Utility functions for Fourier transforms on regularly sampled data.

Functions

dft_postprocess_data(arr, real_grid, ...[, ...])	Post-process the Fourier-space data after DFT.
dft_preprocess_data(arr[, shift, axes, ...])	Pre-process the real-space data before DFT.
realspace_grid(recip_grid, x0[, axes, ...])	Return the real space grid from the given reciprocal grid.
reciprocal_grid(grid[, shift, axes, halfcomplex])	Return the reciprocal of the given regular grid.
reciprocal_space(space[, axes, halfcomplex, ...])	Return the range of the Fourier transform on space.
