最小平方反褶积是把地震子波压缩成尖脉冲，从而使地震记录能够直接反映地下反射系数序列(Least squares deconvolution of seismic waves are compressed into spikes, which can directly reflect the seismic record subsurface reflection coefficient series)

结构动力学分析中，阻尼的几种识别方法，基于时域的参数识别,最小二乘法.....(Structural dynamics analysis, the damping of several methods of identification)

说明：  首先，对复杂振动信号进行EMD分解，得到各个频率分量，接着，对各分量进行Hilbert变换，得到瞬时频率(END resolve,hilbert chang,evry imf,instantaneous frequency)

本文件是一个SPWM逆变器的仿真源文件，可以在MATLAB7.1中直接运行。设计中PWM Generator采用外部调制信号，并在调制信号中注入了三次谐波，很好的抑制了输出谐波，同时提高了直流电源的利用率。(This document is a SPWM inverter simulation source file, you can directly run MATLAB7.1. Design of PWM Generator external modulation signal, and in the modulation signal into the third harmonic, the output of good harmonic suppression, while improving the utilization of the DC power supply.)

svm在matlab环境下多类分类中的一对多分类器类型程序(svm in Matlab environment over classification of the one-to-many types of procedures classifier)

预测控制 DMC算法 用与智能控制系统，实现系统的优化控制(MPC control program is used to analysis the system )

图像识别利用MATLAB或VC编写一个系统，使得该系统能满足信息处理、频域处理、语音增强、识别等内容。(Image recognition using MATLAB or VC write a system so that the system can meet the information processing, frequency domain processing, speech enhancement, recognition and so on.)

说明：  适用Otsu方法做阈值分析。阈值决策的依据是最大类间方差，这种方法的依据就是类间方差，本程序仅仅适用与二分类问题。(thresholding algorithm using Otsu)
