对偏微分方程进行差分计算

This package implements basic Principal Component Analysis 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.

说明：  武汉理工大学程磊编写的AR模型的Burg算法的matlab程序，有用(Wuhan Polytechnic University Hai prepared by the AR model Burg algorithm Matlab procedures useful)

说明：  双馈风力发电系统的PSCAD仿真模型。大家学习下。(Wind PSCAD power system simulation model. We learn next.)

zemax与matlab调用程序，当您用matlab分析复杂数据时，可以利用zemax光路计算工具提供原始数据，由matlab分析，并且可以驱动zemax优化，对自由曲面的优化更为重要，此代码为matlab调用zemax的函数库。(ZEMAX and Matlab : A Powerful Pair ZEMAX features a built-in DDE (Dynamic Data Exchange) server that allows other Windows® applications access to ZEMAX functions. Programming DDE applications can be somewhat complex if you are working in a compiled language such as C++. An alternative is to use one of the scripting languages such as Tcl, Python or Matlab. Matlab is a great choice since it is much more than a scripting language. Matlab provides a wealth of functions for processing and visualizing scientific and engineering data and there are toolboxes for Matlab that extend the basic capabilities into a wide variety of more specialized areas and disciplines. )

说明：  实现基频提取的RAPT算法（一种鲁棒性的基频提取算法）。输入文件为wav波形文件。(A Robust Algorithm for Pitch Tracking (RAPT))

PID Tunning with PSO

[自動控制]CLOSED LOOP POLES計算工具，使用者輸入系統Function(由TF, ZPK, SS, FDS建立)，以及feedback controller，程式會計算出closed loop poles. (CLOSED LOOP POLES calculation tools for automation control. POLE=POLEPLACE(P,C) returns the closed loop system poles for a given plant P and a given controller C. Input P is the given plant (created with either TF, ZPK, SS, or FRD). Input C is the given controller. Output POLE is a vector representing all desired closed loop poles. )

适合MATLAB初学者，可以按着PPT做一些基本练习，可以对MATLAB有个初步的了解(MATLAB for beginners, you can do some basic exercises according to PPT, you can have a basic understanding of MATLAB)

详细介绍了ofdm的发送模块、接收模块及信道估计(Ofdm described in detail the transmission module, receiver module and Channel Estimation)

说明：  这是图论中常用的一些算法的matlab程序！适合建模呢！(This is a graph theory algorithm commonly used in some of the matlab program! Suitable for modeling it!)
