Types of matrices | Matrices | Grade 12 | Math | Khan Academy

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 matrices, and zero matrices. After looking at examples for each, we also figure out what constraints work for elements of each of these matrices.
