用matlab实现的PCA算法，用于人脸检测和识别，人脸图像的特征提取(algorithm of PCA of face detection by matlab)

对信号进行正交相移键控(QPSK)调制，对其理论误比特率和蒙特卡洛仿真的误比特率进行比较 (The signal modulation method is QPSK,compare the theoretical ber and the ber of monte carlo simulation method )

matlab 程序非常适合初学者入门学习，简单，并有详细的注释(matlab chu xue zhe ru men)

说明：  变阶跃式PID控制matlab程序，同大家一同学习。(Variable step-type PID control matlab procedures, with everyone learning together.)

说明：  退火算法程序，经典优化算法，可以找到全局较好的点。(Annealing process, the classical optimization algorithm, can find a good point overall.)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单(This program is the most basic particle swarm optimization algorithm, using Matlab to achieve, is very simple)

MATLAB programs related to electromagnetic wave scattering with special emphasis on wave scattering by random rough surfaces and discrete random media.(Detailed descriptions of the theories and formulations behind these codes can be found in the three-volume book Scattering of Electromagnetic Waves published by John Wiley & Sons: Volume I: Theories and Applications (2000)by L. Tsang, J.A. Kong, and K.H. Ding Volume II: Numerical Simulations (2001) by L. Tsang, J.A. Kong, K.H. Ding, and C.O. Ao Volume III: Advanced Topics (2001) by L. Tsang and J.A. Kong )

很好的matlab程序，大家可以关注一下，主要是做图像的检测的。。。。(Good matlab program, we can look at the main image detection. . . .)

matlab学习资料，对于初学者来说是一本不错的入门教程(matlab learning materials, for beginners is a good introductory tutorial)
