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： ?2d! ^!9
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); CuT~
Bj
net.trainParam.show = 50; B \WIoz;'
net.trainParam.lr = 0.05; [f ._ w~
net.trainParam.epochs = 300; 4~8!3JH39
net.trainParam.goal = 1e-5; %?2: 1o
p = [-1 -1 2 2;0 5 0 5]; E4}MU}C#[
t = [-1 -1 1 1]; hYvWD.c}
net=train(net,p,t); M ~h^~:Lk

但是为什么老是报错： {7F?30: ]
??? Input argument "net" is undefined. !tuN_
