mindchemistry.e3.o3.compose_angles(a1, b1, c1, a2, b2, c2)[source]

Computes the composed Euler angles of two sets of Euler angles.

\[R(a, b, c) = R(a_1, b_1, c_1) \circ R(a_2, b_2, c_2)\]

Note

The second set of Euler angles 'a2, b2, c2' are applied first, while the first set of Euler angles a2, b2, c2' are applied Second. The elements of Euler angles should be one of the following types: float, float32, np.float32.

Parameters

  • a1 (Union[Tensor[float32], List[float], Tuple[float], ndarray[np.float32], float]) – The second applied alpha Euler angles.

  • b1 (Union[Tensor[float32], List[float], Tuple[float], ndarray[np.float32], float]) – The second applied beta Euler angles.

  • c1 (Union[Tensor[float32], List[float], Tuple[float], ndarray[np.float32], float]) – The second applied gamma Euler angles.

  • a2 (Union[Tensor[float32], List[float], Tuple[float], ndarray[np.float32], float]) – The first applied alpha Euler angles.

  • b2 (Union[Tensor[float32], List[float], Tuple[float], ndarray[np.float32], float]) – The first applied beta Euler angles.

  • c2 (Union[Tensor[float32], List[float], Tuple[float], ndarray[np.float32], float]) – The first applied gamma Euler angles.

Returns

  • alpha (Tensor), The composed alpha Euler angles.

  • beta (Tensor), The composed beta Euler angles.

  • gamma (Tensor), The composed gamma Euler angles.
