Create a function for one direction, rotate the 4x4 matrix in 3 directions, apply it and back again. If it was implemented universally in this process, it would have been possible to freely create 5x5, 10x10, etc. not only 4x4, but it was difficult so I hard coding that. So it only works for 4x4 sadly
