该程序是一个用IDL将多个图形绘制在同一个窗口中的实例程序，对初学者很有用(This program is a idl program which plot multiple image in the same window, It is important to new study.)

正三角网格分割球面正三角网格分割球面正三角网格分割球面(Equilateral triangle mesh segmentation spherical programEquilateral triangle mesh segmentation spherical programEquilateral triangle mesh segmentation spherical program)

利用分形和混沌理论，生成十分精美的2维图形。有多种参数可以对图形进行控制。(use fractal and chaos theory, generate very attractive two-dimensional graphics. A number of parameters can control graphics.)

说明：  理科生的浪漫，表白女生，三维心形动态图，还有文字(Romance of Science Students)

【例6.4-1】本例演示：pcolor , contour, contourf的调用格式；等位线标高指令 clabel 的配合使用和区别；colorbar在用户指定位置上创建着色标尺；subplot子图位置的控制；图形窗背景底色的设置。（图6.4-1）(Example 6.4-1 This example demonstrates: pcolor, contour, contourf' s call format the bit line elevation instruction clabel of the used in conjunction with, and differences in the user-specified location colorbar create coloring ruler of the subplot subgraph location control graphics window Background background settings. (Figure 6.4-1))

说明：  电磁波在均匀等离子体中的传输，等离子体密度适中(microwave propagation in uniform plasma)

一种属性离散化的方法，对粗糙集适用(An attribute discretization method, the rough set for)

BMP24位位图量化成256色BMP图，本程序彩八叉树颜色量化。(BMP24-bit quantization into a 256-color bitmap BMP map, this program color octree color quantization.)

本代码用于模拟卫星星下点在地球表面上的投影。可以在程序中给定六要素及其他相关参数，就可以利用MATLAB呈现出仿真图。(The code for a simulated satellite point on the Earth' s surface projection. May be given in the program six elements and other relevant parameters, you can use MATLAB simulation showing a map.)

使用3×1的结构元素，为防止越界，所以不处理最上边和最下边的两列像素(Using 3 × 1 structure elements, in order to prevent cross-border, so I do not deal with the most top and bottom of the two most pixels)
