"Invalid calling syntax for the "ssest" command."

Hello,

I am trying to fit a 2-pole state space model to some timeseries data using the ssest() command, using the code given below:

ttable=array2timetable(vars,'RowTimes',seconds(Time));

sys = ssest(ttable,2,'InputName',["vars1","vars2","vars3","vars4"],'OutputName',["vars5"])

Since this is a MIMO system, the call syntax follows the documentation screenshotted below:

For reference, here is a screenshot of the time table:

Yet, when I try running the script, I get the error shown below:

The error message's only advice is to check the documentation, but what I've done seems like the correct syntax from what the webpage suggests. What am I doing wrong? Thanks very much for any advice!

The syntax is corect, however beginning with R2022b.

From the documentation:

R2022b: Time-domain estimation data is accepted in the form of timetables and matrices

If upgrading is an option, upgrade. Otherwise, you will need to extract the data and use one of the other options.
