scipy.spatial.transform.Rotation.
concatenate#
- classmethod Rotation.concatenate(cls, rotations)#
Concatenate a sequence of
Rotation
objects into a single object.This is useful if you want to, for example, take the mean of a set of rotations and need to pack them into a single object to do so.
- Parameters:
- rotationssequence of
Rotation
objects The rotations to concatenate.
- rotationssequence of
- Returns:
- concatenated
Rotation
instance The concatenated rotations.
- concatenated
Notes
Added in version 1.8.0.
Examples
>>> from scipy.spatial.transform import Rotation as R >>> r1 = R.from_rotvec([0, 0, 1]) >>> r2 = R.from_rotvec([0, 0, 2]) >>> rc = R.concatenate([r1, r2]) >>> rc.as_rotvec() array([[0., 0., 1.], [0., 0., 2.]]) >>> rc.mean().as_rotvec() array([0., 0., 1.5])
Note that it may be simpler to create the desired rotations by passing in a single list of the data during initialization, rather then by concatenating:
>>> R.from_rotvec([[0, 0, 1], [0, 0, 2]]).as_rotvec() array([[0., 0., 1.], [0., 0., 2.]])
