Take the red pill and enter the Matrix!

When we multiply a matrix by a scalar (i.e., a single number) we simply multiply all the matrix's terms by that scalar. We can also multiply a matrix by another matrix, but this process is more …

Matrix multiplication is a way of composing linear transformations, and the convention for matrix multiplication is designed to make this composition of linear transformations work correctly.

Learn about the properties of matrix multiplication (like the distributive property) and how they relate to real number multiplication.

In linear algebra, identity matrices are used to represent linear transformations that do not change the underlying vector space. They are often used as a starting point for solving linear systems …

Matrices can be used to perform a wide variety of transformations on data, which makes them powerful tools in many real-world applications. For example, matrices are often used in …
