Use trial and error with the training subset goal
MSEtrngoal = 0.01*var(trntarget,1) % 1-D target or MSEtrngoal = 0.01*mean(var(trntarget',1)) % Otherwise
Start with the MATLAB default H = 10 and design ~10 nets for each setting of H. Each of the 10 is initialized with a different setting of random initial weights.
