tomodrgn.fft.fft3_center

fft3_center(possibly_batched_vols: ndarray) → ndarray

Batch-vectorized 3-D DFT of even-box sized volume(s) as numpy array Note: numpy promotes default input dtype np.float32 to output dtype np.complex128

Parameters:

possibly_batched_vols – np.ndarray of volumes, shape ([N], D, D, D)

Returns:

np.ndarray of volumes DFT, shape ([N], D, D, D)
