I'm currently learning about matrices in university. I

linear algebra is great BECAUSE it's easy, if you can rephrase a mathematical problem into linear algebra you have tons of tools to help solve it

once you learn about groups (https://en.wikipedia.org/wiki/Group_(mathematics)) you can say a lot about them using representation theory which brings in linear algebraic tools, and a very large part of modern number theory (Langlands program) is done this way

Welcome to the world of brainlets, OP. You have to squander your precious time because they are too fucking stupid to understand high school concepts.

linalg and matrices are a fruitful practice to develop maturity and intuition

>What is the use of matrices.
They are used LITERALLY anywhere, especially in calculus (when differentiating function of multiple variables), they also are part of the theory of differential equations a very important subject both in applied and pure mathematics.

Essentially matrices are the trivial case for linear operators between vector spaces, something which is more extensively studied in functional analysis, also a very relevant topic.

Apart from that it is a good way to train people for more abstract thinking and provide them with skills they will need throughout their math career.

We use it in numerical calculations. Its how Computers do all the magic in solving FEM-problems. Ex: if you want to caluclate the exact time the motor of a car will break under given stress, you'll simulate it on a PC using FEM-methods which in turn use matrices to solve the millions of equations necessary...

Matrices are extremely useful.
I thought you first learnt about matrices in high school

Mapping to differential equations, eigenvalue problems, all of physics. Starts to open your pee brain up to group theory

>>8887889
In my experience the primary utility of matrices is as operators acting on generalized arrays, aka multiplexes

>>8887889
Do americucks teach matrices before teaching what a vector space and a linear function are?

>>8887889
It's the universal representation of linear transformation of finite dimension, that's a big deal, since a lot of things are linear like differentials.

>>8887889
Linear algebra is useful when you mix it with calculus and forms the basis of a lot of complex mathematical analysis later on. Learn it, matrices are fucking awesome man.

get your mind blown sonny.

if you are in CS or any field that is statistics heavy, figuring out how to refactor a problem as a matrix multiplication is almost always step 1

They are easy, anon. Linear algebra is so fucking good. Like no joke. It's so damn cool it makes me sperg in my pants whenever I talk about it. It's the branch of mathematics that first lit that spark for me.

Just stick with it for the time being. It gets better. You're learning the arithmetic right now. Familiarizing you with the most basic concepts. You're learning that 1+1=2. And bit by bit the curtain will be rolled back a bit more until you find you're not just learning algorithms for solving problems, but learning to speak a new language.

Matrix theory is just plain neat

Wait until they teach you neat things like PCA, and eigenfaces

Omfg, yes. Linear algebra before vector and complex analysis. Fucking bullshit ass americucks.
