Targets are incorrectly sized for network.
Matrix must have 18 columns.

matlab高手帮忙解决下，再三感激！
net=train(net,p,t);

看看train的help，要求p和t的列数应该一致。
P
        Ni x TS cell array
        Each element P{i,j,ts} is an Ni x Q matrix.
T
        Nl x TS cell array
        Each element T{i,ts} is a Ui x Q matrix.
