I've been trying to figure out how to extract state and state covariance from multi-object tracker within simulink, but no prevail. It seems like bus selector or selector block can't grab the multi timeseries vector for state and state covariance.
The two pictures is the multi-object tracker for reference and the outputted data in the matlab workspace.

According to my understanding you want to select two outputs after the ‘data concatenation’ block namely ‘State’ and ‘StateCovariance’.
You can use a “MATLAB Function” block in Simulink to extract the desired elements from the multi-timeseries vector. Within the MATLAB Function block, you can write custom MATLAB code to access and manipulate the data. Here's an example of how you can extract the state and state covariance elements using a MATLAB Function block.
function [state, stateCov] = extractStateAndCovariance(data)
state = data.State;
stateCov = data.StateCovariance;
end
