get_rotation_matrix_between_vectors#
- pyxem.utils.vectors.get_rotation_matrix_between_vectors(from_v1, from_v2, to_v1, to_v2)[source]#
Calculates the rotation matrix from one pair of vectors to the other. Handles multiple to-vectors from a single from-vector.
Find R such that v_to = R @ v_from.
- Parameters:
from_v1, from_v2 (numpy.ndarray) – Vector to rotate _from_.
to_v1, to_v2 (numpy.ndarray) – Nx3 array of vectors to rotate _to_.
- Returns:
R – Nx3x3 list of rotation matrices between the vector pairs.
- Return type:
