How to use this Book
This volume aspires to confer understanding of mathematics by visual and intuitive means. It also aims to instill confidence in mathematics, but by numerical verifications rather than by proofs. Detailed proofs are strictly an affair between the Mathematician and his Creator.
The research material exploited in this work dates from before 1900. The main theorems are products of giant minds, and academics have since verified them in a variety of ways. No one seriously doubts the validity of this mature part of mathematics. It could thus be taken as our cultural heritage, not to be questioned or revised.
The problem is how to incorporate mathematics into one's stock of knowledge and skill. The author believes the answer is learning by doing. The doing need not extend to first principles, however. To save time, one should compile blocks of knowledge, which later can serve as tools for more advanced tasks. It is important to inspect the structure of a tool, in order to gain confidence, but each tool can soon be regarded as a black box. The next step is to understand what the tool can do for you, and here simple, practical demonstrations are preeminent.
In this book, we learn to master mathematics by means of the MATLAB program package, which contains a large number of tools, in the form of black boxes. The essential purpose is to verify that these tools produce results in agreement with known results of mathematics.
Here are a few principles to keep in mind while working with this book.
Do not be afraid of making errors. The computer does not go up in smoke, and by correcting errors you learn the syntax of MATLAB.
It is not enough to read the book. It shows a large number of results, but running the files yields additional figures that are essential to understanding.
Typing command lines and files is a way of learning. These lists express the principles and practice of mathematical verification, and the command words constitute the language of MATLAB.
As you work with script files, take the opportunity of displaying more than is normally shown. A statement closed by a semicolon does not display numerical values, but you can gain more insight by peeking at intermediary results. When you have learnt what is hidden, close the statement again.
Be inquisitive! Do not accept MATLAB statements until you understand what they do. Make a small test of your own, on one line if possible, otherwise by a short script file. Occasionally modify examples in the book to watch the effect.
Allot time for the exercises. Some of them are simple variations of examples in the same chapter. Others expect you to be more independent. The important thing is to be active.
Learn by doing!
