This simple library implements the quaternion algebra in Matlab using the isomorphism between quaternions and R^4.
It also implements the rotation matrices for many combinations of Euler angles and the Rodrigues' Formula and the quaternion version.
This library also contains a 3D Visualization tool.

The sum and subtraction is normally performed by Matlab as R^4 vectors.
