采用matlab编写的角点提取程序，可以方便的提取几何图像的所有角点，配有图像(prepared using Matlab corner extraction procedures, to facilitate the extraction of all geometric image corner, equipped with image)

采用matlab中的函数对图像进行放大缩小，缩小到原来的0.2倍，再放大到原来大小(Using matlab function image zoom, narrowed to 0.2 times, and then zoom to the original size)

说明：  这是基于量子遗传算法的函数寻优MATLAB代码。(This is a function optimization MATLAB code based on quantum genetic algorithm.)

用于建立主成分分析模型，三相光伏逆变并网的仿真，MinkowskiMethod算法 。( Principal component analysis model for establishing, Three-phase photovoltaic inverter and network simulation, MinkowskiMethod algorithm.)

说明：  matlab 数字信号处理 FFT的频谱信号分析Matlab示例程序(The MATLAB signal spectrum analysis)

系统辨识教材，个人认为很不错，希望对大家有用！(The system identification teaching material, I believe is very good, hoped that is useful to everybody!)

说明：  k-均值聚类算法c语言版，经验证测试是可以运行

已实现了MATLAB下的音频AGC，效果还可以，做起来才发觉比较简单，关键是要有高效的算法。如果能在实现AGC的同时做到噪音消除和回音消除，则效果更佳。(MATLAB has been achieved under the audio AGC, the effect can be done only to find relatively simple, the key is to have efficient algorithms. If you can do while in the realization of the AGC noise cancellation and echo cancellation, the better.)
