matlab: zero loop in neural network -


everyone! wanna have neural network loop. create neural network

net = newff(rand(5, 100), rand(1, 100), [3, 2], { 'tansig' 'tansig'}, 'traingdx3', 'learngdm', 'mse'); net.layerconnect(1, 1) = 1; net.layerweights{1, 1}.delays = [1];  net.trainparam.epochs = 100;  net = train(net, rand(5, 100), rand(1, 100));

and 

net.lw  ans =       [3x3 double]              []    []     [2x3 double]              []    []               []    [1x2 double]    []

but when view net.lw{1, 1} , get

net.lw{1, 1}  ans =       0     0     0      0     0     0      0     0     0

why loop weights zeros?
