OSTU最大类间方差阈值分割算法matlab实现(OSTU Otsu threshold segmentation algorithm matlab implementation)

在给大家上传一个MATLAB角点检测的程序，希望对大家有用，(To the U.S. to upload a MATLAB corner detection procedures, in the hope that useful to everybody,)

说明：  用于进行变量降维的matlab程序，大家可以试一试，很有效哟(Variable Reduction Testbench MATLAB modules，it is very effective， we can try, very effective ..............)

DC to DC converter with simple full bridge converter

it is used to count the coin in the box using matlab

matlab simulink buck电路的 PID 仿真模型 matlab 2010以上可用(matlab simulink DC-DC chopper buck PID model matlab version 2010)

很好很全的程序哦！jerk系统的多涡卷混沌仿真！(Very good and very full program! Multi scroll chaotic simulation of jerk system!)

说明：  实现数字水印的嵌入，提取，以及受攻击后的提取(The realization of digital watermark embedding, extraction, and the extraction after attack)

1)编写DFT子函数（计算并画出幅频特性），以后可调用。 2）N=32，M=32，128，256时，分析频率分辨率、频谱的光滑程度。 3）N=64，256，512时，分析频率分辨率和频谱的光滑程度。 (1) the preparation of DFT Functions (calculated and drawn amplitude-frequency characteristics), the future can be called. 2) N = 32, M = 32,128,256, the analysis of the frequency resolution, the degree of smooth spectrum. 3) N = 64,256,512, the analysis of the frequency spectrum resolution and the degree of smoothness.)

说明：  这个是MIMO-OFDM的仿真程序，还有对程序的注释以帮助读者理解程序(This is the simulation materials for MIMO-OFDM. And there are also some notes to help the readers to understand the codes.)
