这本书是一个短，重点介绍MATLAB，全面 数学和技术计算软件系统。它将 是有益的到bothbeginning和有经验的用户。它包含简洁 必要的MATLAB命令，以及容易理解的解释 使用MATLAB的编程功能的说明，图形 能力，和桌面界面。它还包括一个介绍 到Simulink，MATLAB的系统仿真的同伴。(This book is a short, focused introduction to MATLAB, a comprehensive software system for mathematics and technical computing. It will be useful to bothbeginning and experienced users. It contains concise explanations of essential MATLAB commands, as well as easily understood instructions for using MATLAB’s programming features, graphical capabilities, and desktop interface. It also includes an introduction to SIMULINK, a companion to MATLAB for system simulation.)

一个简单的在figure中用鼠标画直线的例子。最终是想在matlab环境下编一个用鼠标画贝塞尔曲线的程序，现在正在研究中。(A simple figure using the mouse in a straight line drawn examples. Ultimately would like to matlab environment made a Bezier curve with the mouse painting process, now being investigated.)
