本文分析了语音数字信号的采集来源以及其预处理。通过实例，利用Matlab对语音信号进行时频变换与分析，同时构造一个固定频率的干扰信号，对两个信号进行合成，设计数字滤波器，实现对语音信号的F IR、IIR滤波处理，最后在时域和频域中对信号进行分析比较。(This paper analyzes the sources of voice digital signal acquisition and its pretreatment. By example, voice signals using Matlab time-frequency transform and analysis, and construct a fixed-frequency interference signals, the two signal synthesis, design digital filters to realize the speech signal F IR, IIR filtering, and finally time domain and frequency domain signal analysis and comparison.)

用matlab实现了2dpca算法，基于ORL人脸数据库，识别率较高(Matlab achieved with 2dpca algorithm, based on the ORL face database, the higher recognition rate)

用于初学者学习径向基函数神经网络，可以了解径向基函数神经网络的预测程序。对径向基函数神经网络有一个大体的了解。(For beginners to learn the radial basis function neural network prediction program can understand radial basis function neural network. Radial basis function neural network has a general understanding.)

说明：  Matlab的系统经典辨识，包括二阶和三阶(Matlab system identification classical)

说明：  用matlab提取语音信号，并进行处理，提取语音信号的特征参数(programed by matlab ,a very good thing)

基于matlab编程，仿真。matlab编程百例有助于熟悉matlab基本编程命令，最好成为编程高手。小数据量法求lyapunov指数源程序，可以减轻做混沌控制与同步研究的编程苦恼。(Matlab-based programming, simulation. 100 cases of familiar programming matlab help matlab command of basic programming, preferably as a programming expert. Method of small amount of data source lyapunov index can be done to alleviate study of chaos control and synchronization of programming distress.)

reconstruct image with an input image with interference fringe (use fft2, ifft2, angle)

Various blurring effect and also it will be displaying you image with blind deconvolution.

在MATLAB中，使用LMS算法实现自适应均衡器，通过改变收敛因子和滤波器阶数就可以仿真均衡器的收敛速度和精度。(In MATLAB, use the LMS algorithm adaptive equalizer by changing the order of the convergence factor and the filter can simulate the equalizer on the convergence speed and accuracy.)
