之字扫描，是在JPEG压缩中使用的一个数据扫描格式。自己在MATLAB中编程实现了正反函数。(zigag scanning is a mode of data scanning in JPEG data hoop.This codes realize the zigzag scanning and the inverse zigzag scanning.)

I have thoroughly study the basic of image compression techniques. From that I have selected SPIHT algorithm for my research work. I have implemented on image compression for gray images using SPIHT algorithm. Image compression is implemented using this algorithm has better result over the previous result on gray images and also improved PSNR value high but on other side low result on compression ratio.

模糊pid纯matlab程序.m文件,步骤很详细(Fuzzy pid pure matlab program. M files, the steps in detail)

运用matlab实现霍夫曼编码，可以自己输入(Using MATLAB to achieve Hoffman encoding, you can input it yourself)

In mid-2003, someone in the Lounge asked for a list of time zones. I said that I had one, but the data was in a CodeBase/FoxBase file. Chris Maunder asked if I could retrieve that data and submit it to CodeProject. After procrastinating a few weeks, I decided to go ahead and not only extract the data, but to write a program to edit that data.

说明：  用Matlab/Simulink研究2ASK(DPSK)在加性高斯白噪声信道下的误码率性能与信噪比之间的关系；试用Matlab/Simulink研究2ASK(DPSK)+信道编码（取汉明码）在加性高斯白噪声信道下的误码率性能与信噪比之间的关系(Matlab/Simulink additive white Gaussian noise channel 2ASK (DPSK) the relationship between performance and signal-to-noise ratio of the bit error rate trial Matlab/Simulink study 2ASK (DPSK)+ channel coding (whichever is the Hamming code) in Canada the relationship between performance and signal-to-noise ratio of Gaussian white noise channel BER)

pagerank的一个简单改进，用来识别核心节点。(A simple improvement of PageRank is used to identify core nodes.)

从图片中找出连同区域，保留有三个以上的圆的连同区域(Find out the connection areas, and keep areas with three or more circles)

粒子群算法解决经典的TSP问题，自己做的，测试不错，可以用(Particle swarm algorithm to solve the classic TSP, do it yourself, test good, you can use)
