Why not train neural network newff?

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.

load ('trenovaci_modely2_stredni')
D = [stredni_tvar{1,:}];
F = [stredni_tvar{2,:}];
[ I N ] = size(D) % = ?
[ O N ] = size(F) % = ?
net_stredni_MLP = newff(D,F,20);
net.trainparam.epochs = 100;
net = train(net_stredni_MLP,D,F);
% The trained model is net, NOT net_stredni_MLP!
% D = stredni_tvar{1,7}; DELETE
D7 = D(1,7) % WHY JUST ONE POINT??
% J = sim(net_stredni_MLP,D); DELETE
% save net_stredni_MLP DELETE
J7 = sim( net, D7); % Only 1 point
J = sim( net, D ); % N points
save net
disp('Neuronová síť byla uložena')
Hope this helps.
Thank you for formally accepting my answer

Your workspace dimensions do not make sense. If you have one O-dimensional target vector for each I-dimensional input vector, then at least one of the dimensions of the input matrix and target matrix has to be the same. Then, transposing if you have to
[ I N ] = size(input)
[ O N ] = size(target)
What is
size(stredni_tvar)?
