magtomo.Reconstruction.tensor_gradient#
- tensor_gradient(tf, rot, difference, pol, order)#
Calculates the tensor gradient for a specific orientation.
- Parameters:
- tfnp.ndarray
The current guess for the tensor field.
- rotnp.ndarray
The rotation matrix describing the sample rotation
- differencenp.ndarray
The difference between the projection from vf and the input.
- polnp.ndarray
The polarization at which the projection was measured.
- orderint
The interpolation order for performing rotations.
- Returns:
- np.ndarray
The gradient for this combination of inputs.
