GA

本程序是信息论与编码课程中常见的一种编码方式，即算术编码。这是一种最基本的简单编码(Information theory and coding of this procedure is a common curriculum in the encoding that the arithmetic coding. This is a basic simple coding)

matlab图像处理代码，基本上常用的都包含在里面了，挺好的，适用于基础学习。(matlab image processing code, basically common are included in the inside, and quite good for basic learning.)

matlab仿真出圆孔的夫琅禾费衍射，其中有四副图，原图，二维衍射图样，函数图象和三维衍射图样(matlab simulation of a hole in the Fraunhofer diffraction, which has four maps, original, two-dimensional diffraction patterns, functions, images and three-dimensional diffraction pattern)

非常好用的卡尔曼滤波程序，里边还有一个word文档说明，希望对大家有帮助(Is very nice of kalman filtering program, containing a word document, I hope it can help you )

Cauchy probability distribution function sample

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.

1、本程序用于仿真里德-穆勒（Reed-Muller）码在AWGN信道中的性能，调制采用bpsk 2、理论请参见《差错控制编码》（第二版），Shu Lin（美）编，晏坚等（译）一书P70-75.且仿真结果与书中图4-2完全一致 3、BPSK_AWGN_RM_Code.m为主程序，点击运行即可 4、The_creation_of_RM_code.m和RM_Decode.m分别为RM码的编、译码程序，而Majority_logic_decision.m用于译码中的大数判决，combine_dunction.m用于计算组合数。(1, the procedure for the simulation Reed- Muller (Reed-Muller) codes in AWGN channel performance, modulation using bpsk 2, theory, see " Error Control Coding" (second edition), Shu Lin (America) series , Yan Jian, etc. (translated) book P70-75., and the simulation results consistent with the book Figure 4-2 3, BPSK_AWGN_RM_Code.m-based program, click Run to 4, The_creation_of_RM_code.m and RM_Decode.m were RM compiled code decoding process, and in large numbers for decoding Majority_logic_decision.m judgment, combine_dunction.m used to calculate the number of combinations.)

运用P-Q分解法来进行潮流计算，数据调用需要用到excel(PQ decomposition method using flow calculation, data upload need to use excel)

matlab例程，非常好用，便以移植,bianyuxuxi(susan Algorithm is very easy to use, then to transplant)

一种用贝斯定理的形式基于压缩传感测量估计基本信号(employ a Bayesian formalism for estimating the undering signal based on compressive-sensing measurements )
