在matlab R2009b调试通过，BP神经网络用于函数拟合与模式识别，用于信号特征提取、信号消噪，这个有中文注释，看得明白，到达过程是的泊松过程，仿真效率很高的。-In matlab R2009b debugging through, BP neural network function fitting and pattern recognition, For feature extraction, signal de-noising, The Chinese have a comment, understand it, Arrival process is a Poisson process, High simulation efficiency.
