BP神经网络预测—matlab程序出错，求大神帮忙分析下

title('newff & newcf')
legend('原始数据','newff结果','newcf结果,0)
Error using network/train (line 325)
Inputs and targets have different numbers of samples.

P,T是归一化的结果，用了两种不同的代码运行，结果都是Error using network/train (line 325)
Inputs and targets have different numbers of samples. 请问，是归一化的数据不对，还是隐含层设置不对，还是代码哪里有误？请各位大神帮帮忙，非常感谢！

大哥，在ff=newff(P,T,13);前面加一句

P=P';
T=T';

看看是不是您要的效果
