How do computer programmers use matrices?

Computer programmers use matrices in various ways, primarily for representing and manipulating data in applications like computer graphics, scientific computing, and machine learning. In graphics, matrices are essential for transformations such as rotation, scaling, and translation of images and 3D models. In machine learning, they are used to organize datasets and perform operations on large sets of numerical data efficiently. Additionally, matrices are utilized in algorithms for solving systems of equations, optimization problems, and more.
