Python random rotation matrix generators (currently in 2D and 3D). Generate uniformly distributed random rotation matrices in 2D and 3D. The 2D case is trivial. The 3D case is based on an algorithm ...

You are given an n x n 2D matrix representing an image, rotate the image by 90 degrees (clockwise). You have to rotate the image in-place, which means you have to modify the input 2D matrix directly.

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
