Dear all
I have three time series of experimental data. Each time series includes 3 input variables and one output variable. Using the catsamples command I turn the 3 input and outpup data series into two proper cell arrays Input and Output (uploaded in here).
In ntstool, choosing the option cell I can introduce my Output cell array. The tool succesfully recognizes that it includes 3 time series with 5598 timesteps of 1 element with 5
as shown below: Targets 'Output' is a 1x5598 cell array of 1x3 matrices, representing dynamic data: 3 series of 5598 timesteps of 1 element.
Nevertheless there is not an option to introduce the Input cell array, sine it has dimensions of 3x5598.
Is this a limitation of the tool? Is there another way to train the NARX? Could you please send me a script that fixes this problem?

Hello
With a closed-loop NARX prediction you just need the 1st value or so.
I think my answer to this question could be what you need..
I hope this helps.

multiple outputs are not possible?
