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： BkJNu_{m?
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); -iySU 6
net.trainParam.show = 50; M2rgB%W)m
net.trainParam.lr = 0.05; *,#T&M7D
net.trainParam.epochs = 300; >Ni<itze$i
net.trainParam.goal = 1e-5; |n*<H|
p = [-1 -1 2 2;0 5 0 5]; b Fwc >
t = [-1 -1 1 1]; woyeKOr
net=train(net,p,t); c5AEn -Q

a = sim(net,p) (C60HbL
plot(p,t,p,a,'o') ![hVTZ,hyZ
但是为什么老是报错： N Ty0NH
??? Input argument "net" is undefined. v|#}LQZ
