In this video, we look at a few different types of matrices and how they form subsets of other types. We look at row matrices, column matrices, square matrices, diagonal matrices, scalar matrices, identity …

Ever wondered where row and column matrices show up in real life? In this video, we’ll uncover their practical applications, break down their definitions, and conclude with interesting examples that offer …

In order to mutiply two matrices, the number of columns in the first matrix has to be the same as the number of rows in the second matrix. Here, you're trying to multiply a 2x2 matrix by a matrix with 3 …

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 computer graphics to …

What you will learn in this lesson As long as the dimensions of two matrices are the same, we can add and subtract them much like we add and subtract numbers. Let's take a closer look!

So you're not just blindly doing some-- matrix-matrix products can be pretty tedious, but now you know what they're for. They're actually for the composition of two transformations where each of A and B …

If we think about a matrix as a transformation of space it can lead to a deeper understanding of matrix operations. This viewpoint helps motivate how we define matrix operations like multiplication, and, it …

Sal gives an example of a multiplication of two matrices that don't have the same dimensions.
