Saving Timeseries out of Workspace as Matlab file

So I have a Simulink Modell which I let run automatically via Matlab Skript. I will load in the Modell different Kp and Ki Values for the PI-Controller. Then I have to look if the System is stabil. This is already working and I also get via eigen-values a clue if it is stabil. I have to save them which I do by ploting them.

But I also have to save some timeseries data which I already get from Simulink into my Matlab Workspace via the [TO Workspace Block]. I cant make leftclick and save as because I doing all this in a loop. So I need a code which allows me to save the Timeseries Data as a Matlab file automatically. Best even a counting one, so I dont overright my older saves just because the all have the same name. I hope someone can help me. I already tried

saveas(timeseriesname,[path.mat]);

I found this Code in the Internet where someone also saved timeseries with it (at least what he said). But for me its not working because of the Error: "Invalid handle".

P.s.: Sorry for my bad english :)

Hi Sascha

As per my understanding, you want to save a variable (containing a timeseries) in a .mat file with a dynamic name.

This can be easily achieved using MATLAB's save function.

Please refer to the following article for more details about the save function: Save workspace variables to file.

You can use the following code as a starting point:

count = 1;

for i = 1:10
    filename = "myTimeseriesFile" + string(count);
    % get timeseries into the workspace from your simulink model
    timeseriesVar = timeseries(1:10); % dummy timeseries for demo
    save(filename, 'timeseriesVar');
    count = count + 1;
end
