How do I use an M-by-N matrix input or an M-by-N matrix target in the NNTOOL GUI from the Neural Network Toolbox?

I would like to use an M-by-N matrix input or an M-by-N matrix target in the NNTOOL GUI with the Neural Network Toolbox.

The following example demonstrates how to do this.

At the MATLAB command prompt, type:

PNEW=rand(11,45); %You have 11 inputs to your network

TNEW=rand(5,45);% You have 5 targets to your network

nntool %starts the Neural Network gui

In the Neural Network GUI:

1. Import the data PNEW as 'Inputs' and TNEW as 'Targets' by using the Import button.

2. Create a new Network with the following information:

 Network Type:               Feed-Forward backprop

 Input ranges:               select PNEW from the dropdown menu

 Training Function:          TRAINLM

 Adaption learning function: LEARNGDM

 Performance function: MSE

 Number of Layers:           2

For the Properties of Layer 2, the number of neurons should be 5. The transfer function can be TANSIG.

3. Click on View for the network you created.

4. In the Training Info under the Train tab, select the Inputs as PNEW and Targets are TNEW

5. Click on 'Train Network'
