I'm using the Neural network toolbox narx function but when I try to run the app, it says Undefined variable or network. Does anyone know how to fix this?

I have put in my data into the NARX function and have not changed any of the default settings. I have also tried the examples given by Matlab but I am getting the same error. I am fairly new to Matlab, does anyone know how I can fix this? It's urgent. Thanks.

It appears that you do not have access to the Neural Network Toolbox. You can check this by running the following command:

>> license checkout 'neural_network_toolbox'

If the output is 0 you do not have the Neural Network Toolbox downloaded.

If you are a student at a university, the personal downloads typically do not include toolbox downloads. However, computer labs, and other on campus computers may have the toolboxes.
