Extract Code From System Identification Toolbox

Hi, I am using the system identification apps for my project. I wonder if there's a way to extract the code from the apps so that I can still use the same method but can also make few changes on my data. Thank you.

It has been a fair while since I looked at those. If I recall correctly, the answer is Yes, you could extract the code.

It might take you a few weeks of digging into the implementation of the apps if you do not happen to have experience in how apps are put together and how to to trace through them, but I think it is doable.

I would suggest that it might be easier for you to describe what kind of identification you are doing, in which case someone might be able to point out which MATLAB computation functions are being used.

This is supported by System Identification app. Here is a quick example

1, Open app >> system identificaiton iddata1

2, Estimate a NLARX model and get a new model "nlarx1" in the app workspace

3, Double click "nlarx1" to open the model dialog. "Diary and Notes" contains the code you want.
