# clifford: Geometric Algebra for Python

`clifford` is a numerical Geometric Algebra (a.k.a. Clifford algebra) package for python.

Geometric Algebra (GA) is a universal algebra which among several other independent mathematical systems, subsumes:

• Complex numbers
• Quaternions
• Linear algebra

Scalars, vectors, and higher-grade entities can be mixed freely and consistently in the form of mixed-grade multivectors. Like this,

## Quick Installation

Requires Python version >=3.5

Install using `conda`:

``````conda install clifford -c conda-forge
``````

Install using `pip`:

``````pip3 install clifford
``````

Detailed instructions

## Quickstart

Try out a notebook in binder

Or have a go on your own pc:

```from clifford.g3 import *  # import GA for 3D space
from math import e, pi
a = e1 + 2*e2 + 3*e3 # vector
R = e**(pi/4*e12)    # rotor
R*a*~R    # rotate the vector  ```

## Syntax Summary

Syntax Operation
| Symmetric inner product
<< Left contraction
^ Outer product
* Geometric product
X(i) Return the section of the multivector X of grade i
X(ei) Return the section of the multivector X for which ei is the pseudo scalar
X[i] Return the i'th coefficient from the multivector X
X.normal() Return the normalised multivector so that X*~X is +- 1
