RS码编译码程序,已经调试过的，可以直接使用，啦啦啦啦啦啦啦啦啦啦啦(decode of RS)

可以提取一幅图中想要的目标，多抽样率信号处理，计算多重分形非趋势波动分析。( Target can be extracted in a picture you want, Multirate signal processing, Calculate the multifractal trend fluctuation analysis.)

用模拟退火求解非线性规划的具体例子，很有提高，希望大家能学习学习(Nonlinear programming using simulated annealing)

实验名称:投资组合分析 实验性质：综合性和研究探索性 实验目的：熟练运用投资组合工具箱，学会构造有效前沿组合的方法，掌握最优投资组合的计算方法；给出投资组合VaR 的值。 实验任务：选择股票并从万得下载数据，计算证券的预期收益率、标准差和协方差，设定一组约束条件，构造最优投资组合并计算该组合的Var值。 实验设备：计算机 实验软件：Matlab2013 Wind数据库 选择一组股票作为投资标的，构造投资组合，通过估计收益率均值、计算方差、协方差，计算该投资组合权重、在险价值、画出有效前沿。(Experimental Name: Portfolio Analysis Experimental nature: comprehensiveness and research exploration The purpose of the experiment is to skillfully use the portfolio toolbox, learn to construct effective frontier portfolio method, grasp the best investment portfolio calculation method, and give the value of portfolio VaR. Experimental tasks: select stock and download data from Wan De, calculate the expected return, standard deviation and covariance of securities, set up a set of constraints, construct the optimal portfolio and calculate the Var value of the portfolio. Experimental equipment: computer Experimental software: Matlab2013 Wind database A group of stocks is selected as investment target, and a portfolio is constructed. By estimating the mean value, variance and covariance of the yield, we calculate the portfolio weight, value at risk and draw effective frontier.)

首先要对样本进行聚类分析，以此来确定模糊规则个数。利用K-means法对样本聚类。(First cluster analysis of samples, in order to determine the number of fuzzy rules. Method using K-means clustering of the sample.)

This is the OFDM-DWT mmodel for OFDM modulation and demodulation. it has DWT and IDWT models

说明：  这是一个运用matlab实现复杂网络蓄意攻击和随机攻击 的源代码，欢迎下载，可直接调用。(This is a source code which uses MATLAB to realize deliberate attack and random attack on complex network. Welcome to download and call it directly.)

说明：  边缘方向直方图matlab程序，直方图为提取8个方向的的统计概率(Edge direction histogram matlab program, the histogram for the extraction of eight directions of the statistical probability)

直方图均衡法的MATLAB图，经过测试没有问题，绝对可以用，做图像的同学可以用来参考.大家可以下载下来在MATLAB中运行试试(Histogram equalization method of MATLAB figure, after test no problem, absolutely, can be used to do image can be used for reference)

利用MATLAB画出一个立方体，并通过一种简单仿射变换矩阵得到变换的立方体(Use of MATLAB draw a cube, and through a simple affine transformation matrix get transformation of the cube )
