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： d)04;[=
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); IU Y> ih
net.trainParam.show = 50; \);.0
net.trainParam.lr = 0.05; * MSBjH|
net.trainParam.epochs = 300; pKt-R07*
net.trainParam.goal = 1e-5; AezvBY0'`z
p = [-1 -1 2 2;0 5 0 5]; ~!nLbK2
t = [-1 -1 1 1]; xH_A@hf;
net=train(net,p,t); & Fg|%,fv]

但是为什么老是报错： NX zU0
