Hi
I have a question. I have trained a neural network and for example I had 1000 Inputs, 70 are used for training. 15% for validation and 15 % for testing and now outputs are shown and the network is trained. I want to understand how an I extract the validation and test data in command window of MATLAB. For example if I have an input matrix 3*1000. and my out put matrix is 2*1000. so the validation matrix will be 3*150. How can I show this matrix and finally its related out put in command window of MATLAB ?
Thanks a lot

The input matrix contains train, val and test data. Similarly for the output data.
Indices are available in the training record tr
[ net tr Y E Xf Af ] = train(net,input,target,Xi,Ai).
Type, without a semicolon
tr = tr
for other useful information.
Hope this helps.
Thank you for formally accepting my answer

Hi, thanks for response, but I trained my network with fitting tool, I mean nnstart and then fitting tool, this tool choose 15 of data as validation and 15 as test data, how can I extract them?
