说明：  介绍了如何使用matalab对信号系统进行仿真，对初学者很适用(This text contains a comprehensive discussion on continuous and discrete time signals and systems with many MATLAB&reg examples. It is written for junior and senior electrical engineering students, and for self-study by working professionals. The prerequisites are a basic course in differential and integral calculus, and basic electric circuit theory.)

lecture series of matlab

说明：   学习matlab的朋友，这是一个计算线性方程组的程序，略有改进，若有疑问不吝赐教(learning Matlab friends, which is a calculation of linear equations procedures, a slight improvement If in doubt wing)

truss solver with bridge

matlab下实现DDC的设计,包括CIC，HB，Fir的设计。(Realization matlab DDC design，including CIC,HB,Fir filter.)

说明：  通信系统的模拟仿真程序，可以根据需要建立自己的仿真模型(communications system simulation process can be required to establish their own simulation model)

Weighted Squares Least Estimation

说明：  关于圆盘耦合摆的研究，将介绍单圆盘耦合发电机模型和双圆盘耦合发电机模型的非线性方程组。通过对方程组的分析和MATLAB模拟计算，指出前者电流有稳定的周期解，后者在两圆盘角速度不同时可能进入混沌态，并且通过数值计算其Lyapunov指数（其中一个，出现了正值）来证明其混沌态(Research on the disk coupled pendulums, will introduce the model of a single disc and double disc coupling generator generator model coupled nonlinear equations. Equations through the analysis and MATLAB simulation, that the former current of a stable periodic solution, which is not the same in the two-disc angular velocity may enter the chaotic state, and by numerical calculation of its Lyapunov index (one of which, there have been positive) to prove the chaotic state)

说明：  EMD降噪程序，与stanford开发的小波工具箱和小波降噪工具箱联合使用！(EMD noise reduction procedures, and stanford Development Toolbox Wavelet Toolbox and Wavelet combination!)

SIFT特征点匹配,内涵matlab语言、c语言，(SIFT feature point matching, meaning matlab language, c language,)
