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： {JF"PAS7
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); JAT%s
%UC
net.trainParam.show = 50; 'f CSP|
net.trainParam.lr = 0.05; ~$hR:I 1
net.trainParam.epochs = 300; q03+FLEfC
net.trainParam.goal = 1e-5; %5 nEyZOq
p = [-1 -1 2 2;0 5 0 5]; T8Q _JQ
t = [-1 -1 1 1]; )d2:r 07a
net=train(net,p,t); 1}+b4 "7]

a = sim(net,p) Upcx@z J
plot(p,t,p,a,'o') lNl.lI\t)y
但是为什么老是报错： MUGoW;}v )
??? Input argument "net" is undefined. pZ3sp!
