The notes I uploaded are correct, but what you might have written on your paper is not.
In the last example, when applying transformations to a set of vertices, the vertex matrix should be padded with ones in the third row, so that the points are expressed in homogeneous coordinates. The matlab code we wrote right after was correct.
