In the course, you will flesh out the class definition files for two important Lie group descriptions related to robotic systems, $SE(2)$ and $SE(3)$. The default implementation is homogeneous matrix form. You are free to use other compatible representations so long as the specifics are kept internal to the class.

The code stub for $SE(2)$ is located se2.m and that for $SE(3)$ is located se3.m. In both cases, downloading the file may lead to one with all lowercase letters. You should change the filenames to use uppercase letters.
