说明：  matlab 源代码,五点差分格式,可以直接运行,用于其他方面(matlab source code, a five-point difference scheme can be run directly for other areas)

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.)

matlab的音频指纹提取, 小波包, 需要用到voicbox工具箱(matlab audio fingerprint extraction, wavelet packet, need to use voicbox Toolbox)

”BP.m“文件是BP神经网络整个模型的源程序； “train.fig”是训练时最后得到的图片； “程序运行的人口数量原始数据.fig”是预测结果绘制的图； “程序运行时matlab命令窗口的内容.txt”是运行程序是在matlab命令窗口显示的东西； “程序运行完产生的数据.mat”是程序运行完毕产生的数据。 .bmp文件和.fig文件一样()

有关 matlab 的行业的书籍 可以做下参考(Books about matlab industry can make a reference)

利用电磁场的源激发方法来计算近场FDTD模拟点光源空间传播,用Matlab编写(The source of electromagnetic fields to stimulate the use of methods to calculate the near-field FDTD simulation of point light sources in space communication, prepared using Matlab)

舵机的具体控制，方法简单实用，程序量小，经调试好使。(The specific servo control method is simple and practical procedures for a small amount so that by the debugging.)

hi all this is the 1st file which its contain no thing

matlab 的三象逆变仿真源代码，比较实用，谢谢(matlab simulation of the three inverter as source code, more practical, thanks)
