1.边缘检测，分别用Sobel, Laplacian-Gaussian 方法对一幅灰度图像进行边缘提 取，并给出对比结果； 2.灰度阈值分割：利用双峰法对一幅灰度图像进行灰度分割处理。(1. Edge detection, respectively Sobel, Laplacian-Gaussian methods on a gray-scale image edge extraction, and gives comparative results 2. Gray threshold segmentation: Using Twin Peaks method a gray image gray-scale be dealt with separately.)

matlab仿真出刀刃的夫琅禾费衍射，其中有四副图，原图，二维衍射图样，函数图象和三维衍射图样(matlab simulation of the cutting edge of the Fraunhofer diffraction, which has four maps, original, two-dimensional diffraction patterns, functions, images and three-dimensional diffraction pattern)

OFDM与最小二乘算法，含有几个例子，希望对大家有用(OFDM and the least square algorithm，Contains a few examples，Hope to be useful)

说明：  本代码采用了adaboost算法进行仿真进行人脸检测，很好的给出了仿真图。(it uses adaboost to dtecte face. and it shows the pictures.)

使用MATLAB对DSB-AM进行仿真：双边带幅度调制的过程以及对其中所包含的对信号的频谱分析都可以通过MATLAB中的M语句及相关函数来实现。假如信号m(t)=cos(m)以dsb-am方式调制载波c(t)=cos(20*pi*t),所的信号为y(t)，并将采样频率定为 fs=100Hz,则可在MATLAB中设计程序对该幅度调制的结果进行仿真，绘制已调信号波形和频谱分析。(It is a example for DSB-AM based on MATLAB .)

这个是我对于模糊pid控制自己进行的simulink仿真，很有用。(This is my fuzzy pid control themselves for the simulink simulation, very useful.)

实现模糊控制的程序，在Matlab上实现仿真(the procedure of fuzzy control)
