After I read the instruction of neural network. I found that R2006 has to divide the samples into training, testing and validation. But this seems to be canceled after R2007a version. Is that correct? Matlab will automatically divide them into 3 groups? 

I have no idea with what exactly the toolbox is doing :S 

Thanks.
