hello,

unfortunately my English isn't the best, but I hope you understand the following question and may provide a solution.

I wrote a more or less complicate matlab programm which produces, among others, some linear systems. At a certain point of the programm I want to use the ident tool (GUI-tool of the system identification toolbox) to analyse these systems. Instead of opening the tool and clicking import... for each system I want to load the systems programmatically. Is there any possibility o do this. Something like import2tool(system1,system2)? It is possible to do something like this with the ltiview tool. The command is ltiview('current',sys1,sys2, h); But for some reasons I would prefer the ident tool.

thanks in advance

Good question. I have same desire to be able to generate models programmatically and then call the ident gui to analyze them. I've tried saving data (data & model objects) to .mat files with .sid extension. But ident doesn't accept these files.

Any developments in this area?

No, there is none. If you have saved a GUI session (.sid file) with certain systems and datasets, you can load that session by typing ident('sessionname')

You could alternatively figure out the command being run to produce the model (double clicking on the name of the model shows the code for estimating it). Then you could just run that command rather the use the GUI.
