# 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.
