Simulink is a graphical extension to MATLAB for the modeling and simulation of systems. In Simulink, systems are drawn on screen as block diagrams. Many elements of block diagrams are available (such as transfer functions, summing junctions, etc.), as well as virtual input devices (such as function generators) and output devices (such as oscilloscopes). Simulink is integrated with MATLAB and data can be easily transferred between the programs. In this tutorial, we will introduce the basics of using Simulink to model and simulate a system.

说明：  matlab 中的时频分析工具箱，含有大量的仿真程序(Time-frequency analysis toolbox inmatlab )

说明：  关于增加高斯白噪声的代码，对信号加上高斯噪声的仿真(Gaussian white noise to increase the code, the signal plus Gaussian noise simulation)

FFT的实现的Matlab代码，利用Matlab来实现FFT，从而计算DFT(The Matlab code for FFT)

说明：  基于matlab的一种人脸检测算法，可以检测人脸，可以识别人脸 (face )
