说明：  声子晶体平面波展开的程序，其中参数可以自己设定，直接可用！(Phononic crystal plane wave expansion of the program, where the parameters can be set directly available!)

本文给出了二进制粒子群算法的源程序，并运用实例进行了验证。(In this paper, the source code of the binary particle swarm algorithm is given and verified by an example.)

用EWMA（garch（1，1））模型进行计算，rolling window的形式(use the method of rolling window size equals to 250, adopt EWMA model which also calls Garch(1,1) to calculate the Value at Risk)

说明：  聚类算法，密度聚类，高效聚类，无监督聚类，快速聚类(Clustering algorithm, density clustering, efficient clustering, unsupervised clustering, fast clustering)

基于matlab 设计的滤波器程序，很实用。内容包括 FIR数字滤波器的设计、IIR数字滤波器的设计、FFT频谱分析及应用等。(wave filter of matlab )

实现粒子群算法，里面有代码，大家可以放心的使用，里面程序是可以用的 。(fgfggfg)

this file give simulation for Single Input Dual Output 16-QAM Simulation with comparison in SER between Selective Combining,Equal Gain Combining and Maximum Ratio Combining methods

基于DCT数字水印算法的Matlab实现源代码,1. 将文字水印和图像水印转换为二值序列水印； 2. 对水印进行置乱，提高其安全性； 3. 选择合适大小的块，给出DCT域中频分块编码方案；(DCT-based digital watermarking algorithm Matlab source code, a text watermark and image watermark converted into a binary sequence watermark .. 2 watermark scrambling to improve their safety 3 Select the appropriate size of the block, given DCT domain frequency block coding scheme )

neural network back propagation

说明：  这是我从网上摘抄下来的，关于matlab语法与常用函数要点，供大家一起学习。(This is the excerpt from the Internet down, on the matlab function of grammar and common elements for all to learn together.)
