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： %vil ~NU
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); = ;cTm5d;T
net.trainParam.show = 50; |z7V1xF
net.trainParam.lr = 0.05; uc>":V
net.trainParam.epochs = 300; V1&qgAy~
net.trainParam.goal = 1e-5; \i'Z(1
p = [-1 -1 2 2;0 5 0 5]; X- ZZLl#
t = [-1 -1 1 1]; F )Iz:
net=train(net,p,t); Fq$r>tmV

但是为什么老是报错： ]|-sZ<?<i
??? Input argument "net" is undefined. K9{RU4<
