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： vbWJhj K0h
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); iO? g F
net.trainParam.show = 50; 2w x[D
net.trainParam.lr = 0.05; Y uw
E 0
net.trainParam.epochs = 300; (!_X:+0_
net.trainParam.goal = 1e-5; }P&1s,S8J#
p = [-1 -1 2 2;0 5 0 5]; ,NaV
[ "9$
t = [-1 -1 1 1]; 4 [5lX C
net=train(net,p,t); A{i][1N

但是为什么老是报错： r21?c|IP
??? Input argument "net" is undefined. |iwM9oO%
