The Best Way to start MATLAB - Written by a MATLAB beginner -

This is a very beginner's book for those new to MATLAB who are just starting to work with MATLAB.
MATLAB is a high-performance programming language for scientific and engineering calculations. In recent years, AI tools have been introduced that can perform both basic and advanced calculations and are becoming essential tools for AI learning. However, they are expensive to purchase individually.
We will assume that this will be done on a PC with MATLAB already installed. It was originally created to handle matrix calculations easily. Later, functions such as GUI and graph drawing were added, and it is used not only in the fields of electrical engineering, mechanical engineering, mathematics, physics, and information, but also in the humanities, such as economics and statistics. MATLAB is expensive and difficult to get started with, so people tend to shy away from it. However, MATLAB has been adopted by companies and other organizations due to its powerful computing capabilities and graphical GUI, and there is no reason not to use it.
There are also free software programs that are equivalent to MATLAB, such as Octave and Silab. Octave in particular is compatible with MATLAB.
In this book, I, as a MATLAB ultra-beginner, will explain the very basic use of MATLAB without using simlink, as well as a few applied uses of MATLAB. The operation in this manual has been verified with MATLAB 2022b. Also, there is no mention of AI in this document. (There is a bit of AI in the last 10 lines.)
