直接序列扩频（DS）原理的仿真程序，通过该程序你可以很好地理解直接序列扩频原理。(Direct Sequence Spread Spectrum (DS) The principle of simulation program, through the program you can very well understand the principle of direct sequence spread spectrum.)

用matlab对视频文件(*.avi）进行读取，读取出每祯的图片，选取出自己感兴趣的图片，还原成新的视频文件，如程序显示无法读取，下载winavi进行转换(Using matlab for video files (*. avi) to read, read Qizhen each picture, select a picture of interest to them, to restore into a new video file, such as the program displays can not be read, download WinAVI to convert)

MATLAB程序代码，测试图像灰度平均值的程序，希望对大家有用。(MATLAB program code, test the image gray mean value of the program, I hope useful for everyone.)

实现了粒子群优化bp神经网络在锅炉燃烧优化中的应用，有详细的代码解释，仿真图例，运行时将程序名改为程序内的function命，运行即可(Particle swarm optimization bp neural network applications in boiler combustion optimization, detailed code interpreter simulation legend, change the name of the program to function within the program life runtime can run)

1采用遗传算法对男女生样本数据中的身高，体重，喜欢数学，喜欢文学，喜欢运动，喜欢模式识别共6个特征进行特征选择，并基于所得到的最佳特征采用SVM设计男女生分类器，并计算模型预测性能（包含SE,SP,ACC和AUC ）。提示：可以用6位的0/1进行编码，适应度函数可以考虑类似 。(1 genetic algorithm for boys and girls in the sample data of height, weight, like math, like literature, like sports, like pattern recognition feature a total of six feature selection, design and use of SVM classifier for boys and girls based on the best features of the resulting and calculating prediction performance model (including SE, SP, ACC and AUC). Tip: 6 may be encoded with the 0/1, the fitness function may be considered similar.)

this is the file which will help in understanding the MATLAB and simulink good luck
