[[math]]

basically arrays of arrays

in game dev primarly used for stacking transfomations on each other
3x3 in 2d 4x4 in 3d
despite most transformations being able to be represented with position rotation and scale, it doesnt account for perspective transformations which compose most 3d games so you cant just 3x3 the shit unless you want an orthographic view, and going 3x3 and sending that into the gpu jsut to convert it is unoptimized
