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.
Hope this helps
Thank you for formally accepting my answer
