One use for matrix math is in programming 3D engines for video games. A single point on the screen can be defined as a vector. The TV or computer screen is two-dimensional only, so to create the look of depth, objects must change size as they come closer to the viewer or go farther back into the scene. An image is made up of hundreds or thousands of vectors. By multiplying this set or matrix, you can change its size. You can also multiply the vector array by another array, which allows you to rotate the image. In rotation, parts of the image become ...
