matlab 数字水印，dct变换，嵌入水印，简单易懂，方便学习(dct matlab)

As was pointed out to investigate the behavior of synchronous generator using a simple model (model steady state) is not sufficient so that the equations obtained in the dq. For simulation models to make them as equations of state:

将宽频带系统的输出仿真到窄频带输出的方法。(Broad-band system will be output to a narrow band output simulation approach.)

围绕粒子群的当前质心对粒子群重新初始化.这样，每个粒子在随后的迭代中将在新的位置带着粒子在上次搜索中获得的“运动惯性”（wvi）向Pi，Pg的方向前进，从而可以在粒子群的运动过程中获得新的位置，增加求得更优解的机会.随着迭代的继续，经过变异的粒子群又将趋向于同一点，当粒子群收敛到一定程度时又进行下一次变异，如此反复，直到迭代结束.(particle swarm around the center of mass of the current PSO reinitialization. Thus, Each particle in the next iteration will be in the new location with particles in the last search was the "inertia" (wvi ) Pi, Pg orientation, and thus can PSO course of the campaign was a new position, increase seek better solutions opportunities. With the continued iteration, after variation of PSO will tend to the same point. When PSO converge to a certain extent when the next variation, so repeatedly, until the end of iteration.)

HHT变换工具箱，里面含有EMD，边际谱等程序。希望大家喜欢(HHT conversion kit, which contains the EMD, the marginal spectrum and other procedures. Hope you like)

这是一个NSCT的工具箱，用与图像融合等图像处理MATLAB程序。(nsct_toolbox use in image fusion)

对数据进行分组：通过该程序在matlab将一组数据随机的分为两组，用于建模计算(devide into two groups)

This code is used for broad and narrow weed leaf classification
