How do we know how well the gnn reconstructs the target state vector from the truth vector captured by the sensors?

In the "Multiplatform Radar Detection Fusion" example, how do we know how well the gnn reconstructs the target state vector from the truth vector captured by the sensors?

Please run the below command in the command window of installed MATLAB R2019a version to get release specific documentation for the "Multiplatform Radar Detection Fusion" example:

1. The "trackErrorMetrics" object is used to calculate the tracking accuracy, which is a counterpart of the track assignment metrics object. Please run the below command in the command window of installed MATLAB R2019a version to get release specific documentation about the "trackErrorMetrics" object.

2. In the "Tracking Closely Spaced Targets Under Ambiguity" example, you can see an outcome of the track error metrices. You can click on the "helperRunTracker" function to see it in use.Please run the below command in the command window of installed MATLAB R2019a version to get release specific documentation for the "Tracking Closely Spaced Targets Under Ambiguity" example

3. In the "Passive Ranging Using a Single Maneuvering Sensor" example, you can see another example of it being used. Look for the lines of code in the "Track Using an EKF in Cartesian Coordinates" section.Please run the below command in the command window of installed MATLAB R2019a version to get release specific documentation for the "Passive Ranging Using a Single Maneuvering Sensor" example:
