主要用于sar成像算法学习，用来生成目标回波，并用RD算法进行成像处理。(Sar imaging algorithm is mainly used for learning, used to generate the target echo imaging with RD algorithm.)

soumekh的SAR成像源代码，非常翔实经典！(soumekh SAR imaging source code, very informative classic!)

这是一个半导体激光器弛豫振荡现象的仿真程序，计算参数和速率方程模型都取自经典教材Semiconductor Lasers(Agrawal 著)，可以作为学习和进一步研究半导体激光器各种动态特性的基础材料。(This is a simulation program by Matlab for calculating the oscilating in semiconductor lasers, in which the rate equation model and the parameters used are all from the classic technical monograph by Agrawal. This could be a basic material for further investigating and studying different dynamic activities of semiconductor lasers. )

模拟退火算法，经过调试可以运行，效果不错(simulated annealing algorithm which has been tested with good performance)

基于simulink的Jiles模型参数提取。使用中需使用simulink的parameter estimation功能(Jiles artheron model parameter extraction based on simulink)

this file is the identification of the fermentation process using an inventive method to define Q-matrix which uses Matlab commands to define the time consuming derivative operations which simplifies the simulation and also reduces the calculation burden of the users. this m.file is a complete simulation of a chemical fermentation process which is done in Matlab. this job includes an on-line estimationn of the states of a control system and also the identification of the parameters of process. this work can be considered an identification research project to a great extent.

讲述了机械故障诊断中一些理论知识，如现在常用的HHT，对初学者有帮助。(Tells the story of some mechanical fault diagnosis theory of knowledge, such as the now commonly used HHT, help for beginners.)

基于Kaimal谱与线性自回归(AR)法，生成脉动风速。(Based on Kaimal spectrum and linear autoregressive (AR) method, the pulsating wind speed is generated.)
