2D Matrices
Matrix is a very powerful tool for manipulating vectors. By mastering how to use matrices, you can freely translate, scale and rotate shapes. Since the technique can be equally applied to anything expressed by vectors, we will look at many more advanced use of matrices later in this book. Matrices may look complex at a first glance, but you'll find it very handy and useful as you get used to the concept. Let's practice here and learn basics with simple examples.
