PCA主成分分析算法用于人脸识别的例子。此算法是基于矩阵特征值的排序而提取出主要成分的。(PCA principal component analysis algorithm for face recognition example. This algorithm is based on the ranking of the matrix eigenvalue extracted principal components.)

说明：  无线通信原理系统应用中用到的MATLAB仿真，对与学习无线通信原理及MATLAB都很有帮助滴(pricinples of communication system simulation with wireless aplications with MATLAB)

实现神经网络PID进行编程，仿真，此神经网络是BP神经网络。(Realize the neural network PID programming, simulation, the neural network is BP neural network.)

正交频分复用，应用在水声通信中。正交频分复用，应用在水声中(Orthogonal frequency division multiplexing applications in underwater acoustic communications. Orthogonal Frequency Division Multiplexing, used in the sound of water)

说明：  关于雷达建模的一本书中很详细的Matlab代码，第3章：连续波和脉冲雷达。(Matlab code about radar system simulation, chapter3: continuous wave and pulsed radar.)

一个菜单界面，分别用菜单命令来绘制原数据曲面图，线性插值，最近点插值，3次多项式插值，3次样条插值后的图形，每次插值都可以在同一图形界面下比较插值前后图形。(A menu interface, respectively, using the menu command to map the original data surface map, linear interpolation, nearest point interpolation, polynomial interpolation 3 times, 3 times after spline graphics, interpolation can be per- under the same graphical interface graphics compared before and after interpolation.)

For a thorough description of the norms, see the Chapter 4 of Robust and Optimal Control, Zhou, Glover, Doyle 1996. Here the point is to give some lines of code illustrating what are the H2 and Hinf norms of LTI systems. In that sense, it is also illustrated that the H2 norm is smooth in the space of the system parameters, whereas the Hinf norm is non-smooth locally Lipschitz (since it is a min-max problem, thus prone to the waterbed effect ).

一个基于Music算法的DOA估计程序，该程序为Matlab的图形用户界面的形式，方便各种参量的仿真！(A estimation program of DOA based on Music aigorithm. It is convenient to simulate many situation!)

该算法是根据自适应差分脉冲编码调制原理编写的算法，该算法利用了语音信号样点间的相关性，并针对语音信号的非平稳特点，使用了自适应预测(The algorithm is based on principles of adaptive differential pulse code modulation written algorithm, which samples the voice signal using the correlation between, and for non-stationary characteristics of speech signal using an adaptive prediction)
