You are going to have to design many candidate nets to decide the number of hidden nodes and which random weight initialization will yields the best net. If you have a lot of data, you can just use the default dividerand with the default train/val/test ratio = 0.7/0.15/0.15 . However, if this isn't satisfactory, you could change it to 0.666/0.167/0.167/. However, it really isn't worth the trouble.
If you don't have much data you might want to use divideind to specify which inputs belong to each trn/val/test subset.
How many people are there? If there are Np people you could use one input from each person in every group of Np.
Hope this helps.
