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： f*~fslY,o
net=newff([-1 2; 0 5],[3,1],{'tansig','purelin'},'traingd'); ;CZcY] ol
net.trainParam.show = 50; ~k(Ez pn#
net.trainParam.lr = 0.05; !;a <E:
net.trainParam.epochs = 300; ATH z~a
net.trainParam.goal = 1e-5; J"MJVMo$T
p = [-1 -1 2 2;0 5 0 5]; 5=986ci$U
t = [-1 -1 1 1]; u\wd<<I']
net=train(net,p,t); OXB-.<

但是为什么老是报错： U8KY/ !XZ
??? Input argument "net" is undefined. mK-:laIL"
