The primary goal of this chapter is to help you to become familiar with the MATLAB® software, a powerful tool. It is particularly important to familiarize yourself with the user interface and some basic functionality of MATLAB. To this end, it is worthwhile to at least work through the examples in this chapter (actually type them in and see what happens). Of course, it is even more useful to experiment with the principles discussed in this chapter instead of just sticking to the examples. The chapter is set up in such a way that it affords you time to do this.
