tfft.nudft

nudft(source, points, grid_shape=None, transform_type='type_2', fft_direction='forward')

Compute the non-uniform discrete Fourier transform.

Warning

This function explicitly creates a dense DFT matrix and is very computationally expensive. In most cases, tfft.nufft should be used instead. This function exists primarily for testing purposes.

For the parameters, see tfft.nufft.
