Les méthodes géométriques sont les méthodes les plus répandues en simulation indoor. On a cité les principales familles de ces méthodes. Il s’avère qu’il n’existe pas de meilleures méthodes que d autres. En effet, le choix d’une méthode par rapport à une autre dépend des objectifs principaux qui sont fixés au début du travail. Il est donc fondamental de faire un compromis entre le nombre de rayons à calculer et la complexité de calcul.

将格式为rgb的数字图像转换成格式为hsi的数字图像，方便简单，操作容易(change rgb image into hsi image)

图像域上的DFS遍历，函数返回连通域数量，范围端点以及最大值(DFS traversal on the image domain, the function returns the number of connected domains, the scope of the endpoint as well as the maximum value)

说明：   倒立摆系统是研究控制理论的实验平台，它的行为与火箭飞行以及两足机器人行走有很大相似性，因而对其研究具有重大的理论和实践意义，一直是控制界关注的焦点。以直线单级倒立摆作为研究对象，采用最优控制策略实现对其平衡控制，进行仿真实验设计。(Inverted pendulum control theory is to study the experimental platform, its behavior and the rocket s flight and walking biped robot is very similar, and thus their study is of great theoretical and practical significance, has been the focus of attention control. Inverted Pendulum on a straight line as the object of study, the optimal control strategy to achieve their balance control, a simulation design)

S-Function（系统函数）为扩展Simulink® 的性能提供了一个有力的工具。以下下节阐述了什么是 S-Function，为什么可以使用S-Function，以及怎样编写自己的S-Function。(S-Function (system function) for the expansion of the performance of Simulink ® provides a powerful tool. The following section describes what is under the S-Function, Why you can use the S-Function, and how to write your own S-Function.)

对经过椒盐噪声处理的图像进行均值滤波和中值滤波的MATLAB程序，可直接运行得到图形结果（原创）。(The Median filter and Mean filter for a figure processed by salt and pepper noise.)

dirver shall implement this function by read & msk.

This is a JPEG encoding & decoding program of still image. It does not use level shifting. Discrete Cosine transform (DCT) is performed both by classical & Chen s Flowgraph methods. Predefined JPEG quantization array & zigzag order are used here. RUN - LEVEL coding is used instead of Huffman coding. Compression ratio is compared for each DCT method. Effect of coarse and fine quantization is also examined. The execution time of 2 DCT methods is also checked. In addition, most energatic DCT coefficients are also applied to examine the effect in MatLab 7.4.0 R2007a. Input is 9 gray scale pictures & output is 9*9=81 pictures to compare. Blocking effect is obvious. (This is a JPEG encoding & decoding program of still image. It does not use level shifting.
