MATLAB: How to add one more hidden layer to ANN wizard

Question

I am using ANN wizard (nnstart) to run neural networks for fitting (prediction) purposes. According to the results, it appears adding one more hidden layer would produce a better predictability. However, the wizard doesn't have the capacity to add more hidden layers.

Could anyone please advise what I need to do to run a 3 layer ANN (2 hidden and 1 output) using the wizard?

Thanks

A second hidden layer will not improve performance if your single hidden layer model is optimized.

size(input) = ? size(target) = ?

Type of network = fitnet?

No. of Hidden nodes= ?

NMSE = mse(target-output)/mean(var(target',1)) = ?

What is your NMSEgoal ? <= 1/100 ?
