Cannot split data for train, validation and test set in neural network

Hello, I want to train a recurrent neural network but I only found one example from the document, and my problem is the training did not split the data set for training, validation and test set even I excuted the code for splitting as the following:

 %data conversion
 X = con2seq(X);
 T = num2cell(T);

 %configure RNN
 net = layrecnet(1:2,3:5);%3 hidden layer,2 time step
 [Xs,Xi,Ai,Ts] = preparets(net,X,T);% prepare input to get time series for training

%training, validation, test split
 net.divideParam.trainRatio = 70/100;
 net.divideParam.valRatio = 15/100;
 net.divideParam.testRatio = 15/100;

     net = train(net,Xs,Ts,Xi,Ai);% training the net
     view(net);

     Y = net(Xs,Xi,Ai);% get prediction
     perf = perform(net,Y,Ts);% show the performance

Please tell me where the problem is.

Thanks,

Eason

Hi Eason,

The above method code is indeed the right way of splitting data. To get a perspective on the question, what make you think the network is not splitting the data?
