新手求助~（关于初级的神经网络问题）
各位大虾，我在网上看到的教程里的一个程序段，本来想要试试看的： +NbiUCMX
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); F ^Bk @
net.trainParam.show = 50; !_FTy^ @c2
net.trainParam.lr = 0.05; }2 Tq[rl~s
net.trainParam.epochs = 300; >qs/o$+t}
net.trainParam.goal = 1e-5; [(eX\kL
p = [-1 -1 2 2;0 5 0 5]; 5mS/,fs@
t = [-1 -1 1 1]; et "Pb_-U
net=train(net,p,t); <<b]v I

但是为什么老是报错： \KzH5 ?
