How to use multiple input-output datasets in ssest function (MIMO System Identification Toolbox).

I'm using ssest function for MIMO system identification. (https://jp.mathworks.com/help/ident/ref/ssest.html)

• This article says how to use input-output data in the timetable format as a single dataset, but I'd like to know how to use multiple input-output datasets.
• Additionally, I would like to know how to specify the C matrix as the identity matrix in advance, and then estimate the A and B matrices using ssest function.

The article also describes how to use the tt input to describe MIMO data sets (and for multiple experiments if that's needed): link

Or use the u,y input: link

To specify the C matrix as the identity matrix and esimate only the A and B matrices, it looks like the init_sys input provides a way to constrain the structure of the estimated model, see this link for an example.
