二维粒子群的实现。 编码简单，容易理解。(Two-dimensional particle swarm implementation. Coding is simple, easy to understand.)

此程序适用于matlab环境下对图像进行匹配 就是用一副模板图像去和现有图像进行匹配从而实现图像的识别 (this is a duocument about BlockMatchingAlgoMPEG)

这个是无线传感器网络的DV-hop算法，对初学者很有用，可以看看。(This wireless sensor networks DV-hop algorithm, useful for beginners, you can see.)

2014“深圳杯”数学建模夏令营B题 基因组组装 将读长序列组装成基因组,能较好地解决测序中可能出现的个别碱基对识别错误、基因组中存在重复片段等复杂情况.(2014 Shenzhen Cup Mathematical Modeling Camp B title Genome assembly Assembled into the read length genomic sequence, preferably the nucleotide sequence of the particular solution of recognition errors may occur, the presence of complications, etc. repeats genome.)

利用matlab,基于传输矩阵平面波展开法计算一维光子晶体能带结构。(The energy band structure of one-dimensional photonic crystals is calculated by using MATLAB and plane wave expansion method.)

说明：  MATLAB前推回代法配电网潮流，节点数任意修改(MATLAB- Power Flow of Distribution Network Based on Forward and Backward Substitution)

SMI方向图和性能(波束形成算法，自己修改） 优点： 收敛速度快 缺点：1 当阵元输出含有较强的期望信时，或者期望信号与干扰信号相关时，性能急剧下降.2 由于权向量含有方向矢量，因此对阵列的幅相差非常敏感；3 ,期望信号的功率不能过大，比干扰信号相差几十dB，也就是说，在小期望信号、大干扰信号情况下，也可进行SMI处理。 (SMI pattern and performance (beamforming algorithm, make changes to) Advantages: fast convergence Disadvantages: 1 output when the array elements with strong expectations of the letter, or related to the desired signal and interference signals, the performance sharply .2 direction vector containing the weight vector, so the array is very sensitive to the amplitude difference 3, the desired signal The power can not be too large, than the difference between the scores of interference signal dB, that is, in the small desired signal, large signal interference case, SMI can also be handled. )
