用Matlab对图像进行哈夫曼编码（Huffman Coding）以实现对图像的无损压缩(Use Matlab to realize Huffman coding for lossless image compression)

说明：  HSV颜色空间较RGB空间更适合人的感官视觉，在HSV空间统计图像的分布特征并用于检索比在RGB空间的效果较好。(HSV color space than RGB space is more suitable for people’s senses of sight, in the HSV spatial statistical distribution of the image and is used to retrieve than in RGB space effective.)

随机撒点程序 对随机撒的点进行分类 按距离进行分类(Random scatter point program for random scatter of points clas)

说明：  一些基本的matlab函数，比较常用，希望能够帮助各位初学matlab的朋友们(Some basic matlab function, commonly used, I hope you can help novice matlab friends)

用迭代法在MATLAB中实现（赫姆霍兹）Helmholtz方程组的求解(Solving Helmholtz equation set by iterative method in MATLAB)

This tutorial is intended for those who want to learn basics of MATLAB programming language. Even with a limited knowledge of this language a beginning programmer can write his/her own computer code for solving problems that are complex enough to be solved by other means. Numerous examples included in this text should help a reader to learn quickly basic programming tools of this language. Topics discussed include the m-files, inline functions, control flow, relational and logical operators, strings, cell arrays, rounding numbers to integers and MATLAB graphics.
