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： JAd .\2%Y
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); A;Y~Hu4KPZ
net.trainParam.show = 50; R9R~$@~G
net.trainParam.lr = 0.05; XXum2eA
net.trainParam.epochs = 300; )VkVZf | S
net.trainParam.goal = 1e-5; a<q9~QS
p = [-1 -1 2 2;0 5 0 5]; DSqA}r
t = [-1 -1 1 1]; >W] Wc4 \
net=train(net,p,t); PL&> p M

但是为什么老是报错： L;")C,CwQ
??? Input argument "net" is undefined. 1gK^x^l*f
