龙格库塔法matlab仿真代码。适于学习控制的朋友在进行matlab仿真时学习方法本质。(Runge-Kutta method matlab simulation code. Learning Control for friends during the matlab simulation method when the nature of learning.)

说明：  MATLAB程序实现图像增强、图像去噪等图像处理。(Image Enhancement and Image Denoising)

产生线性调频信号以及均匀脉冲截断的线性调频信号，并分别生成频谱(It generates the lfmcw signal and the lfmcw signal modulated by the uniform pulse sequence, and it also generates the frequency attribution of the two signals.)

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)

在一段文字中嵌入4bit水印，方法是基于系数类嵌入的，经过打印扫描攻击后能正确提取水印(4bit watermark embedded in a piece of text, the method is based on the coefficient of class embedded, after the print scan attack correctly extract the watermark)

这是一个关于模糊同步控制器的仿真程序，相关的参数以及模糊规则都可以在论文中找到，希望能对你们有帮助。(This is a fuzzy synchronization controller simulink, you can find the parameters in the paper. I think it is useful for you.)
