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： X\3IY:Q@T
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); mo%9UL,#W
net.trainParam.show = 50; n"B"A ysz
net.trainParam.lr = 0.05; arf`% 9M
net.trainParam.epochs = 300; + >o/Ob
net.trainParam.goal = 1e-5; nA8]/r 1k
p = [-1 -1 2 2;0 5 0 5]; }>:v
t = [-1 -1 1 1]; zo 66=vE!
net=train(net,p,t); +gb2>fei&

但是为什么老是报错： 8.D$J
