说明：  本章的内容更深入MATLAB可视化功能的内核。编写本章的目的有两个：一，使读者更深入地理解高层绘图指令，从而可绘制出更精细更生动更个性的图形；二，使读者能利用低层图形指令和图形对象属性开发专用绘图函数(This chapter more in-depth visualization of the core MATLAB. The purpose of the preparation of this chapter, there are two: First, make readers more in-depth understanding of high-level graphics commands, which can draw out the finer more vivid and personalized graphics 2, so that readers can use low-level graphics commands and graphics object properties developed special drawing functions)
