实现白光多缝衍射和双缝干涉，得到白光彩色的干涉条纹(Realization of white multi-slit diffraction and double-slit interference fringes get white color)

运用粒子群优化算法对ARMA(p,q)模型的阶数进行优化是可行的，且利用优化后的ARMA模型对航空发电机状态趋势进行分析的结果十分准确，与原始数据所表现出的航空发电机状态变化趋势基本一致。经计算，此时分析结果的平均相对误差较小，仅为1.38 ，与优化前构建的ARMA模型相比，平均相对误差降低0.23个百分点，优化效果明显。(Using particle swarm optimization algorithm to optimize the order of the ARMA (p, q) model is feasible, and the use of the results of the ARMA model optimized air generator status trends analysis is very accurate, and the raw data showed aviation the generator status consistent trend. Calculated analysis of the results, the average relative error is small, only 1.38 , compared with the the ARMA model built before optimization, average relative error is reduced by 0.23 percentage points, to optimize the effect is obvious.)

混沌与分形理论是最新兴起的金融市场理论，这是混沌与分形分析的例程，需要的请自行下载(chaos and fractal theory is the latest emerging financial market theory, which is chaotic and fractal analysis routines. Requests need to download)

说明：  这是MATLAB数值分析里面的小程序，不知道怎样描述好！(matlab)

程序为常规AM，DSB，SSB调幅信号的调制与解调的MATLAB程序，其中单边带调制用两种方法进行调制：一种为频谱直接变换，另一种为希尔伯特变换实现(MATLAB for norm AM,DSB and SSB modulation and demodulation,besides,modulation for SSB,has tow ways:frequency spectrum transform and hilbert transform)

模拟信号采样周期，若频率符合要求，则输出波形与原波形一致(Analog signal sampling period, if the frequency to meet the requirements, the output waveform consistent with the original waveform)

说明：  利用MATLAB进行的画图软件，很齐全，有助于初学者学习画图(Drawing conducted using MATLAB software, it is complete, will help beginners to learn drawing)

it is about sammon map in tha clustering.

matlab编写，能够实现局部子空间鉴别分析，含主方法和测试代码，能直接运行(matlab prepared, can achieve local subspace discriminant analysis, including the main methods and test code that can be run directly)
