介绍了RBF神经网络的基本模型，并根据此模型编写了相关的matlab程序，此程序可以以任意精度逼近目标值，最后可得到网络的训练次数，权值和阈值。-Introduce the RBF neural network model, and write program by matlab according to this model, this procedure can be arbitrary precision approaching the target.Finally we can get the number of training，the weights and threshold values ​ ​ of the last available network.
