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'
