 close all, clear all, clc
 tic
 [ x, t ] = simplefit_dataset;
 MSE00    = mean(var(t',1)) % Constant output reference
 Hmin     = 0
 dH       = 1
 Hmax     = 5
 Ntrials  = 10 
 j        = 0

 for h = Hmin:dH:Hmax

   j = j+1;
   if h == 0
      net = fitnet([]); % Linear Model
   else
       net = fitnet(h);
   end

   for i = 1: Ntrials

       Hiddennodes    = h
       Trial          = i
       net            = configure( net, x, t);
       [net tr y ]    = train(net, x, t);
       stopcrit{i,j}  = tr.stop;
       bestepoch(i,j) = tr.best_epoch;
       NMSE           = mse(t-y)/MSE00;% Normalization
       R2(i,j)        = 1-NMSE;        % Rsquare: See Wikipedia 

    end
 end

 stopcrit  = stopcrit
 bestepoch = bestepoch
 R2        = R2
 toc

Hope this helps
