转载：对神经网络中使用最广泛的一种：BP神经网络采用vbmatlab来实现，把训练数据拷入，load的*.m文件中,

文件中部load的*.m为测试数据

save 存盘的文件为测试数据的bp预测值,

该程序可以扩充n个输入,n个输出,很容易-reproduced : the neural network the most widely used one : BP vbmatlab using neural networks to achieve, it is copyed into the training data. m *. load the document, Central to the paper load *. m to save Inventory test data for the paper test data bp predictive value, The procedure can be expanded to import n, n output, it is easy
