运用matlab7.1开发一个简单的GUI图形用户界面程序，很好的将GUI跟simulink仿真结合在一起，适合初学者参考。(Matlab7.1 develop a simple to use GUI graphical user interface program will be a very good GUI together with the simulink simulation for advanced users.)

提出改进型的节点重构小波包频带能量谱与 PNN（概率神经网络）的联合故障诊断新方法。 有具体的数据和程序，经过本人验证的，程序有效！效果很好！(Joint fault diagnosis node propose a new method for the reconstruction of improved wavelet packet energy spectrum band and PNN (probabilistic neural network). Specific data and programs, after I verified, the program works! Works well!)

离散傅里叶变换，加窗fft解决谐波信号中的频谱泄露和栅栏效应(Discrete Fourier transform, windowed fft solve harmonic signal leakage and fence effect of spectrum)

BP源代码共享！希望对大家有帮助今天编了个预测程序，效果不是很好，但里面一些基本算法希望给刚学的人有所帮助！同时也希望高人帮忙指点一下，我这个程序要怎么样预测效果才会好点，谢谢！(BP to share the source code! Hope everyone has to help today编了个prediction procedure, the effect is not very good, but inside some of the basic algorithm would like to just help people to learn! At the same time also hope that an expert advice to help you, I like this process to predict how the effect will be a good point, thank you!)
