In what area are operations on matrices used?

Question

Mathematics

Where are matrix operations used, such as matrix multiplication?

Answer 1

In computer graphics, and not only matrices. There, in principle, a lot of linear algebra and analytic geometry. Here I think it will be exhaustive for you.
Matrices are, in principle, widely applicable, for example, with the help of them it is convenient to solve systems of linear equations.

Answer 2

OpenGL, GLSL

Answer 3

In programming - every day.
Arrays are also matrices.

Answer 4

1) Computer graphics (3D): DirectX
2) MatLab = Matrix Laboratory. The whole package is based on operations on matrices. The code is very clear and short (no loops needed).

Answer 5

Everywhere! In any section of science and technology you will find where you can apply the matrix. It happens like this. A mathematical model is built that describes some process or object. Such a model is basically a number of equations. Equations can be very different - ranging from simple linear to complex integro-differential equations. Such models are quite bulky, so it is convenient to represent them more compactly in matrix form.
My favorite example is regression.
