Dear all,

I have this code:

P = [c{1,:}];
T = [c{2,:}];
net1 = newff(P,T,20);
net1.trainparam.epochs = 100;
net = train(net1,P,T);
P = s{1,7};
Y = sim(net1,P);

After running the code, nothing happens. Just Comand Window reports name of file. Why not start training network? Does anyone have any idea? How to make this network trains?

You seem to repeatedly make this same mistake:

 net = train(net1,P,T);
 Y = sim(net1,P);
 Now: There are 2 nets: net1 and net
 Question: which is trained and which is untrained?

PS: MLP(Multi-Layer-Perceptron), not MPL

That's what I just don´t know. Because I have this piece of code created from Help in Matlab. I thought that this is the exact syntax. So I don´t know, which one is trained and which aren´t. I need to train the neural network with the given parameters (P,T) and then save this train netwok.
