So consider this a gentle and quick introduction…to the topic.…If you ever took pre-calc in high school,…you may already know that a matrix is an array of numbers…arranged in rows and columns, such as this matrix,…in which nine values are arranged in a square matrix…that's three rows high by three columns wide.…One of the reasons that matrices are used…for creating visual effects is that they enable us…to apply mathematical operations…
