MATLAB: What´s wrong with the neural network´s training

cell arrayDeep Learning Toolboxduplicate postnewff

Dear all,
I have this code for training neural network (type newff) and MATLAB is almost all day busy, but nothing happens (no training newff). Does anyone know, where is the mistake?
load ('trenovaci_modely2_stredni')
D = [stredni_tvar{1,:}];
F = [stredni_tvar{2,:}];
net_stredni_MLP = newff(D,F,20);
net.trainparam.epochs = 100;
net = train(net_stredni_MLP,D,F);
D = stredni_tvar{1,7};
J = sim(net_stredni_MLP,D);
save net_stredni_MLP
disp('Neuronová síť byla uložena')
Thank you for your answers.

 net2 = train(net1,...);
 Now there are 2 nets one trained and one untrained. Which do you think is untrained?
