Linear algebra is a fundamental branch of mathematics that plays a crucial role in fields like computer science, physics, and engineering. This guide will introduce the basics of matrix operations and their practical applications.

What is a Matrix?

A matrix is a rectangular array of numbers arranged in rows and columns. It is a core concept in linear algebra and is often used to represent systems of equations or transformations.

Matrix Structure

Basic Operations

Here are the essential operations you can perform with matrices:

  • Addition: Adding corresponding elements of two matrices of the same dimension.
  • Subtraction: Similar to addition, but subtracting elements.
  • Multiplication: Multiplying matrices involves dot products of rows and columns.
  • Transpose: Flipping a matrix over its diagonal to switch rows and columns.

Applications of Matrix Math

Matrices are widely used in:

  • Computer Vision (e.g., image transformations)
  • Physics (e.g., solving systems of equations)
  • Machine Learning (e.g., data representation)
  • Game Development (e.g., 3D graphics rendering)
