You are correct that the fundamentals (Vectorized computation, aka matrices) are often introduced early on. The level at which you interface with linear algebra often scales with the level of math you are at. You can add them , integrate them , and use them to solve some PDEs . You can see how all these "levels" of linear algebra would be accompanied by another math class pushing you to utilize linear algebra at a higher level than before. It appears that you're at the first level. I've actually never done  in the classroom, but  was introduced to me in a class on differential equations that utilized matrices as a possible solution route.
