Get the model output from system identification toolbox, send it to workspace

Hi,

I have general question about transferring data from system identification toolbox to workspace.

I have estimated my model using Nonlinear ARX - system identification toolbox in MATLAB and got my model. And then I want to transfer the result and graph from "Model Output" to workspace for further processing (plot it as MATLAB figure) but i don’t know how to call it especially the model output graph.

Need some step by step advices.

note: I have exported my model to workspace but I don’t know how to call the model output.

Thank you

Kind Regards

Imam

Hi,

I understand that you want to get the model's output in the workspace. First, ensure your model is exported to the workspace. You mentioned that this have been done, so model variable will be visible in the workspace. The next step involves using the 'compare' function to evaluate the model's performance.

Here is a general example of how to do so:

% Compare
compare(data, nlarx1);

Additionally, you have the option to save the result images directly from the results tab after the model has been estimated, an option to copy the image or to save the image should appear.

I hope this helps!
