Euler angle sequences (Definition)

An Euler angle sequence is a rotation matrix that is completely determined by three parameters, called Euler angles. These Euler angles are represented by the $\phi $ , $\theta $ and $\psi $ variables with each corresponding to a rotation about an axis. There are several different conventions. Only one will be shown here, since it is more important to understand the underlying math thoroughly.

A list of the Euler angle rotation matrices for different sequences
