2010 数学建模大赛 赛前matlab培训5(2010 Mathematical Contest in Modeling Training (numerical entry) lecture 5.zip)

matlab自带的很好用的kmeans算法程序，已经验证通过，(matlab kmeans algorithm, matlab kmeans algorithm matlab kmeans algorithm procedures)

本实验将使用MATLAB 7.0软件分别对20钢的离子渗碳和气体渗碳过程进行模拟，渗碳时间分别为1h、2h、8h、20h，渗碳温度分别为1203K、1223K、1273K、1323K。对20钢的其中一面进行一维气体渗碳，设该扩散系数和界面传递系数均与渗碳浓度无关，对渗碳厚度、渗碳速度、渗碳量和渗碳时间、渗碳温度的关系进行模拟。(In this study, using MATLAB 7.0 software 20 steel ion carburizing and gas carburizing process simulation, carburizing time were 1H, 2H, 8h, 20h, carburizing temperature of 1203K, 1223K, 1273K, 1323K. 20 steel one side of a one-dimensional gas carburizing, set the diffusion coefficient and interface transfer coefficient has nothing to do with the concentration of carburizing, the relationship of the thickness of the carburizing, carburizing speed, carburizing and carburizing time, carburizing temperature simulation.)

说明：  一个基于dct变换的数字水印算法的源程序(A dct-based Digital Watermarking Algorithm source code)

This is a very simple and loose project manager.(This is a very simple and loose project manager. It saves only the following information for each project that is necessary to switch between projects : - Current working directory - Project specific Path - All opened m-files (order is not guaranteed in pm.) - Current active m-file. - List of run configurations you want to execute sequentially. )

说明：  用CA(元胞自动机)判断网络两点之间的连通性(Using CA to determine the connectivity between two nodes of network)

BPSK EGC分集程序，仿真了分集带来的性能增益(EGC diversity gains)

这是一个用在光学测量中的程序，他的作用是产生正弦条纹(This is a program in the optical measurement, his role is to produce sinusoidal fringe)

random spectrum sensinh is the aim of this mfile.

说明：  针对NL-Mreans算法运算时间较长的问题，提出了优化，大大缩短了时间。(To solve the problem of long operation time of NL-Means algorithm, an optimization method is proposed, which greatly shortens the time.)
