自己用的一个求MFCC参数的程序，绝对好用，带原始数据，可直接运行(A program and MFCC parameters, absolutely easy to use, with the original data, and can be run directly)

有约束的情况下的MPC MATLAB程序，可以正常运行，对于想学习mpc控制器的初学者可以参考修改。(Under the constraint of MATLAB, the MPC can run normally, beginners can refer to want to learn the MPC controller changes.)

a simple eigenface program under matlab Imagetest is the picture of the guy you want to find among the 20 guys

Lattice Boltzmann 程序，使用D2Q9模型，模拟流体在多孔介质中的渗流。(procedures, the use of D2Q9 model Simulation of Fluid in the porous medium flow.)

Structured Edge Detection Toolbox( ################################################################### # # # Structured Edge Detection Toolbox V3.0 # # Piotr Dollar (pdollar-at-microsoft.com) # # # ################################################################### 1. Introduction. Very fast edge detector (up to 60 fps depending on parameter settings) that achieves excellent accuracy. Can serve as input to any vision algorithm requiring high quality edge maps. Toolbox also includes the Edge Boxes object proposal generation method and fast superpixel code. If you use the Structured Edge Detection Toolbox, we appreciate it if you cite an appropriate subset of the following papers: @inproceedings{DollarICCV13edges, author = {Piotr Doll ar and C. Lawrence Zitnick}, title = {Structured Forests for Fast Edge Detecti)

某班有N个学生，已知他们参加某次考试的成绩（0~100间的整数），求全班同学的平均成绩。(A class is to have N students, known as their new the result of the examination (0 to 100 between integer),for the whole class average scores.)

OFDM系统通过在时域符号前插入大于信道冲击响应长度的循环前缀（CP）可以避免符号间干扰(ISI)和载波间干扰(ICI)。但是，过长CP会使得数据传输效率降低。可以采用最小均方误差（MMSE）信道缩短均衡技术来压缩信道冲击响应长度。(OFDM systems avoid inter-symbol interference (ISI) and inter-carrier interference (ICI) by inserting a cyclic prefix (CP) larger than the channel impulse response length before the time-domain symbol. However, long CP will reduce the efficiency of data transmission. A minimum mean square error (MMSE) channel shortening equalization technique may be employed to compress the channel impulse response length.)

PCA是一种掌握事物主要矛盾的统计分析方法，它可以从多元事物中解析出主要影响因素，揭示事物的本质，简化复杂的问题。本程序实现了基于PCA特征脸的人脸识别。(PCA is a major contradiction to grasp things, statistical analysis, it can parse out things from multiple main factors, revealing the essence of things, simplifying complex issues. This program implements the features of face recognition based on PCA.)
