In what ways are matrices used in the real world?
In: Mathematics
Former game developer here,
Linear algebra are the bread and butter in 2D and 3D video games and photo/image editing/composition software. A single matrix represents the whole universe, matrices represent rotations, translations, and other transformations, they are stored in hierarchies to represent systems of objects and rotations (think of all the joints in a skeleton), they even represent the camera that gives you a perspective view where things in the distance are smaller, and the whole universe is flattened so it can be mapped to your screen.
Matrices can represent systems, from pipes, to circuits, to traffic.
And matrices are used in the original Page Rank algorithm.
That’s just what I can think of off hand.
