SURF

用costas环实现载波同步。假设发送信号载波频率为3.563Mhz，本地初始频率为3.5628Mhz。程序中直接给出了环路滤波器的参数C1,C2。(this is synchoronization on time recovery basing on matlab)

ABC_to_dq0变换，ABC_to_（aβ）aiphar beta变换以及逆变换的mdl文件，已仿真验证其正确性。(ABC_to_dq0 transform, ABC_to_ (aβ) aiphar' beta transform and inverse transform mdl file, verify its correctness has been simulation.)

一个简单的基于HOG的行人检测程序，MATLAB编写，其中read me文(-A simple HOG based pedestrian detection program, MATLAB write, read me the document which explains in some detail.)

四元数表示的，用于matlab仿真的工具箱。通过它，可以掌握四元数的一些特征。(quaternion said, for the simulation of Matlab Toolbox. Through it, we can get quaternion some characteristics.)

短时傅里叶变换STFT，对脑电癫痫数据的三维显示(Short time Fourier transform STFT, the data on the three-dimensional display of Epilepsy)

MATLAB程序代码，对人数进行统计，对图像灰度进行处理。(MATLAB program code, statistics on the number, carries on processing to the image gray.)

matlab 画地图，非常实用，有需要的可以下载过去！(very strong！)

本代码是赵书兰老师的《MATLAB编程与最优化设计应用》这本书的程序源代码(This code is Zhao Shulan teacher "MATLAB programming and optimization design applications," this book source code)

基于量子的粒子群优化算法,该算法通过粒子群有量子的行为，提高了算法的寻优能力，增强了算法的全局搜索能力，有效的避免了“早熟”问题。(Quantum based particle swarm optimization algorithm.The algorithm improves the searching ability of the algorithm by quantum behavior of particle swarm, and enhances the global searching ability of the algorithm, and effectively avoids "premature" problem.)
