Nural network Simple Fitting Problem has "not enough input argument" massage

Dear all,

I am following the "Getting Started with Neural Network Toolbox" video. As the video says, I tried "Simple Fitting Problem". But when I click "Train", the GUI gave an error pop-up window "Unable to Train Networks: Not enough input arguments".

Does anyone know how to solve this issue? I am using Matlab R2012a, and Neural Network Toolbox Version 7.0.3.

Thanks very much

Xiwang - it might be helpful to provide a link to the video that you are running so that others can get an idea of what steps you are following.

You probably have to transpose the input and target matrices. For N examples of I-dimensional inputs and corresponding O-dimensional targets

 [ I N ] = size(input)
 [ O N ] = size(target)

Hope this helps.

Thank you for formally accepting my answer
