How to get mse, mae and mape separately for multi layer output?

My codes have 2 layer output. But when i run, it only display error values (mse, mae and mape) for single layer output. I don't know whether the error is for first or second layer? Also, i want to get separate error values for each output layer. How do i do that?

Inp=repmat(TInp,1,2);

Out=repmat(TOut,1,2);

[NInp,PS]=mapminmax(Inp)

[NOut,TS]=mapminmax(Out)

[trainInd,valInd,testInd] = divideblock(40,0.5,0.3,0.2);

for i=1:20;

net = feedforwardnet([i,2],'trainlm');

net=train(net,NInp,NOut);

Y=sim(net,NInp);

Targ=mapminmax('reverse',Y,TS);

error=(Out-Targ);

perf=mse(net,Out,Targ);

perf2=mae(error);

perf3=mean(abs(error/Out));

MSE(i,:)=perf;

MAE(i,:)=perf2;

MAPE(i,:)=perf3;

end
