pytransform3d.rotations.check_quaternions¶
- pytransform3d.rotations.check_quaternions(Q, unit=True)[source]¶
Input validation of quaternion representation.
- Parameters:
- Qarray-like, shape (n_steps, 4)
Quaternions to represent rotations: (w, x, y, z)
- unitbool, optional (default: True)
Normalize the quaternions so that they are unit quaternions
- Returns:
- Qarray-like, shape (n_steps, 4)
Validated quaternions to represent rotations: (w, x, y, z)
- Raises:
- ValueError
If input is invalid
