# clifford: Geometric Algebra for Python¶

In [2]: import math

In [3]: a = e1 + 2*e2 + 3*e3  # vector

In [4]: R = math.e**(math.pi/4*e12)  # rotor

In [5]: R*a*~R    # rotate the vector

This module implements Geometric Algebras (a.k.a. Clifford algebras). Geometric Algebra (GA) is a universal algebra which subsumes complex algebra, quaternions, linear algebra and several other independent mathematical systems. Scalars, vectors, and higher-grade entities can be mixed freely and consistently in the form of mixed-grade multivectors.
