hi,
I am trying to create a feed-forward back-propogation network with
3 inputs vetcors, 2 hidden layer with 7 nodes, and 2 output vectors ..the implementation of my algorithm on matlab displays two errors which I believe are the source from output..because when I do any output separelty I have no error..

P=vibrationdata(1:50,1:2:3);
T=vibrationdata(1:50,4:5);
[pn,minp,maxp,tn,mint,maxt]=premnmx(P',T');
net=newff(minmax(pn),[7 1],{'tansig','tansig'},'traingdm')
net.trainParam.epochs=5000;
net.trainParam.lr=0.3;
net.trainParam.mc=0.6;
net=train (net,pn,tn);

les erreurs :
Error using ==> traingdm at 103
Output data size does not match net.outputs{2}.size.

Error in ==> network.train at 107
[net,tr] = feval(net.trainFcn,net,X,T,Xi,Ai,EW,net.trainParam);


please If someone can help me beacause I was really blocked...
