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： $\|$ ekil4
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); uj_ OW re
net.trainParam.show = 50; 9nFPGI z+
net.trainParam.lr = 0.05; tTT./-*0
net.trainParam.epochs = 300; }2^_Gaj
net.trainParam.goal = 1e-5; J? WT
p = [-1 -1 2 2;0 5 0 5]; 0B^0, d(s
t = [-1 -1 1 1]; ))"
*[
net=train(net,p,t); |-Z9-rl

a = sim(net,p) d~](S<k
plot(p,t,p,a,'o') A#gmKS<J/7
但是为什么老是报错： fA!uSqR$V
??? Input argument "net" is undefined. ]o <'T.x
