Why do not Matlab split my inputs into 3 portions, although I've so set?

I've trained a neural network, but the whole data is trained without test and validation. My input is 10000 (vector) and I have 60 of them. My output is 60 (vector) and I've also 60 of them.

p     %% input 
p = con2seq (p);
t     %% target or output
t = con2seq (t);
net = newff(p,t,[2 2]);
net.divideParam.trainRatio=0.7;
net.divideParam.testRatio=0.15;
net.divideParam.valRatio=0.15;
net.trainParam.lr=0.01;
net.trainParam.min_grad=1e-20;
net.trainParam.goal=1e-30;
net.trainParam.epochs=200;
net = train(net,p,t);
