weldx.transformations.WXRotation.magnitude#

WXRotation.magnitude(self)#

Get the magnitude(s) of the rotation(s).

Returns:

magnitude – Angle(s) in radians, float if object contains a single rotation and ndarray if object contains multiple rotations.

Return type:

ndarray or float

Examples

>>> from scipy.spatial.transform import Rotation as R
>>> import numpy as np
>>> r = R.from_quat(np.eye(4))
>>> r.magnitude()
array([3.14159265, 3.14159265, 3.14159265, 0.        ])

Magnitude of a single rotation:

>>> r[0].magnitude()
3.141592653589793
