This package implements basic Principal Component Analysis and Eigen Faces in Matlab and tests is with grayscale portion of the FERET database. Images are not preprocessed and it is up to the user to preprocess the images as wanted, not changing the filenames.

一个阻感回路电流电压波形仿真源码，可以实现simulink模块里不可控的参数调整。(This code includes the U-I simulation in R-L circuit such as welding SCR component。)

最大类间方差法的VC++和matlab源程序，还包括其原理介绍的doc文档(Otsu method of VC++ and matlab source, but also introduced the principle document doc)

自己编写的Matlab程序，解决机器人路径规划问题。欢迎大家多多指教！(own procedures for the preparation of the Matlab solve robot path planning. Welcome to the exhibitions.)

以时滞切换系统为对象，给出了使系统稳定的输出状态反馈器设计条件(Dynamic output feedback control for a class of switched delay)

这是2dof（pi-逆前馈加pid反馈），单纯pid反馈，单纯pi模型逆前馈对应的仿真结果。 其中系统模型采用前面根据pi模型与n4sid算法结合得到的综合模型。(This is 2 dof (PI- inverse feedforward pid feedback), pure pid feedback, pure PI inverse model feed-forward corresponding simulation results. In front of the system model using models based on PI and n4sid algorithm combined with integrated model.)

To keep overall output power per unit cost low, the grid-connected converters should be able to extract the maximum available power from the PV arrays. Since the PV array characteristic is highly nonlinear, maximum power point tracking (MPPT) of the PV arrays becomes rather challenging.

《 MATLAB 程式设计与应用》，网络WEB版本，包含了很多MATLAB的相关示例与代码。(" MATLAB programming and applications" , Internet WEB version of MATLAB contains a number of relevant examples and code.)

非常简单的卡尔曼滤波程序，便于大家学习卡尔曼滤波。(Very simple Kalman filtering program, easy to learn the Kalman filter.)

电力线通信多径信道模型-Manfred Zimmermann模型，多径效应的传递函数H(f)可以用N条传输路径的叠加以及含有频率f、延时τ、距离d的方程来表示： H(f)=∑g_i *A(f,d_i )*e^(-j2πfτ_i ) 式中，i 为路径号， g_i为路径 i的加权系数(包含了传输系数和反射系数的作用)，A(f,d_i )为衰耗，其大小由长度、频率决定，τ_i是每条路径上的延时。 (Powerline Communication multipath channel model-Manfred Zimmermann model)
