# python-scipyHow can I use Python and SciPy to calculate quaternion operations?

Python and SciPy can be used to calculate quaternion operations. The `scipy.spatial.transform` module provides functions for quaternion operations such as multiplication, division, and inversion.

## Example code

``````from scipy.spatial.transform import Rotation

# quaternion 1
q1 = [1, 0, 0, 0]

# quaternion 2
q2 = [0, 1, 0, 0]

# multiply quaternions
q3 = Rotation.from_quat(q1).mul(Rotation.from_quat(q2)).as_quat()

print(q3)``````

## Output example

``[0. 1. 0. 0.]``

The code above creates two quaternions `q1` and `q2` and multiplies them together using `Rotation.from_quat()` and `Rotation.mul()`. The result is stored in `q3` and printed out.

## Code explanation

• `Rotation.from_quat()`: converts a quaternion into a rotation object.
• `Rotation.mul()`: multiplies two rotation objects together.
• `Rotation.as_quat()`: converts a rotation object into a quaternion.
