Which network?
Which outputs?
help train
doc train
Look at the explanation of what outputs are available at the END of training; e.g.,
[net tr Y E Pf Af ] = train(net,p,t,Pi,Ai );
The only information on what happened DURING training is in the structure tr and the command line output. Try
net.trainParam.show= 1;
If you want to obtain a complete history of [net ... Ai], try removing the semicolon.
WARNING: If you try to obtain a history by looping over a succession of 1 epoch training calls, you can get a valid result. HOWEVER, you will not get the same result as that from a single multi-epoch call.
Hope this helps.
