说明：  信号经过滤波器，会发生相移，本程序设计了零相位滤波器，矫正相位(The signal passes through the filter, will occur the phase shift, this procedure designs the zero phase filter, corrects the phase)

该系统使用极其简便，即使 你对各种网络模型不是很深刻的了解，也可以很好的使用该系统。使用时， 你可以自己修改网络的各种参数，交互性较好，而且该系统通过大量的图示 及参数设置，可以让你了解每个应用实例实现的过程及详细步骤。(The system is extremely easy to use, even if you have to various network model is not very profound understanding can be a good use of the system. When used, you can change the network's own parameters, interactive better, but the system through a lot of icon and parameter settings, so you can understand each application process and the realization of detailed steps.)

说明：  随机信号的提取，通过matlab实现微弱信号的提取(Random signal extraction, through matlab to achieve the extraction of weak signal)

说明：  matlab聚类分析代码聚类分析代码聚类分析代码聚类分析代码(cluster analysis cluster analysis matlab code code code cluster analysis cluster analysis code)
