If you want to specify certain elements in a matrix, such as a particular item at a row and column intersection, then you can do so by creating references to those specific items. In this movie, I will show you how to create those references. We'll start simple by creating a small two-by-three matrix, so I will assign it to a variable called A-M-A-T, which, in my head, just means a matrix.
