this is the code of facial recognition system

利用c语言编写的，在matlab环境下运行mex函数可以生成动态的dll库，可以用来计算图像区域的梯度向量直方图特征。(Use c language, in the matlab environment running mex function can generate dynamic dll library that can be used to calculate the gradient vector histogram image area.)

基于嵌入式GUI的设计源码，在windows上开发(based on vc6.0, the GUI of embeded OS)

Simulating V2V and V2I connectivity in Matlab using car following, lane changing models and entry and exit ramps on a 4-Highways, 3-Ramps scenario

对整个图像进行分块，再对每块进行像素点寻找，最后合并块。(cut the picture,then find the pixels which are demanded,finally merge them back to the picture)

DFT in matlab, the code is a example of long time in computation.

Nonlinear Distortion in Wireless Systems: Modeling and Simulation with Matlab一书中的源代码simulink文件.(This book covers the principles of modeling and simulation of nonlinear distortion in wireless communication systems with MATLAB® simulations and techniques In this book, the author describes the principles of modeling and simulation of nonlinear distortion in single and multichannel wireless communication systems using both deterministic and stochastic signals. Models and simulation methods of nonlinear amplifiers explain in detail how to analyze and evaluate the performance of data communication links under nonlinear amplification. The book addresses the analysis of nonlinear systems with stochastic inputs and establishes the performance metrics of communication systems with regard to nonlinearity. In addition, the author also discusses the problem of how to embed models of distortion in system-level simulators such as MATLAB® and MATLAB Simulink® and provides practical techniques that professionals can use on their own projects. Finally, the book explores simulation )
