GO-AHEADの書籍（Scilab Ultra Basics） - 橋平礼の電験三種合格講座

Scilab Ultra Basics

　This is a book for very beginners in Scilab for those who are just starting out with Scilab, a free software and highly compatible with MATLAB before using 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.

　Therefore, we assume that you will first study with Scilab, which is MATLAB compatible software, and then introduce MATLAB. Both MATLAB and Scilab were 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. Although it is often avoided because of its high cost and difficulty for beginners, 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 MATLAB. However, MATLAB is expensive, so the idea is to practice with Scilab first.

　In addition to Scilab, there is also free software that has the same functionality as MATLAB, such as Silab. Octave in particular is compatible with MATLAB.

　In this book, I, a MATLAB-compatible Scilab ultra-beginner, will explain how to use Scilab from the very basics to slightly more advanced applications. The operation in this manual has been checked with Scilab 6.1.1.
