# scipy.spatial.transform.Rotation.inv

Rotation.inv(self)

  Invert this rotation.

  Composition of a rotation with its inverse results in an identity transformation.

  Returns:
    inverse `Rotation` instance

      Object containing inverse of the rotations in the current instance.

  Examples

      >>> from scipy.spatial.transform import Rotation as R
      >>> import numpy as np

  Inverting a single rotation:

      >>> p = R.from_euler('z', 45, degrees=True)
      >>> q = p.inv()
      >>> q.as_euler('zyx', degrees=True)
      array([-45.,   0.,   0.])

  Inverting multiple rotations:

      >>> p = R.from_rotvec([[0, 0, np.pi/3], [-np.pi/4, 0, 0]])
      >>> q = p.inv()
      >>> q.as_rotvec()
      array([[-0.        , -0.        , -1.04719755],
             [ 0.78539816, -0.        , -0.        ]])
