Linear algebra is a branch of mathematics that deals with the theory and application of linear equations, linear transformations, vector spaces, and matrices. It is a fundamental tool in many fields, including physics, engineering, economics, and computer science.
This creates a matrix that looks like:
You can also use other matrix environments, such as pmatrix, vmatrix, and bmatrix, depending on the style you prefer. Here's an example of a 3x3 matrix using the pmatrix environment:
This creates a matrix that looks like:
