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 …

Learn Solving a system of 3 equations and 4 variables using matrix row-echelon form Solving linear systems with matrices Using matrix row-echelon form in order to show a linear system …

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.

Sal solves a linear system with 3 variables by representing it with an augmented matrix and bringing the matrix to reduced row-echelon form. Created by Sal Khan.

Sal solves that matrix equation using the inverse of the coefficient matrix. Created by Sal Khan.

Learn how systems of linear equations can be represented by augmented matrices. A matrix is a rectangular arrangement of numbers into rows and columns. Matrices can be used to solve …

In the video "Tricky Examples of Nonlinear 2D Transformations," the first example looks like it could be used in a video game, such as for creating a ceiling as a player moves through a …

What the matrix is augmented by depends on what you're doing. If you're solving a system of linear equations, the vector containing the solutions is added on the RHS. If you're finding the …
