MATLAB: Can I display position and velocity errors between truth vector and reconstructed vector

Question

In the following example:

https://www.mathworks.com/help/releases/R2019a/fusion/examples/multi-platform-radar-detection-fusion.html

Do we know the quality difference between the truth vector and reconstructed vectors in terms on position (m) and velocity(m/s)?

Is it possible to add position error and velocity error columns to the output?

Answer 1

Yes, They are stored in the variables "truthMetrics" and "trackMetrics".

You can display them in the command prompt using the following commands:

>> disp(trackMetrics)
>> disp(truthMetrics)

You can append them to your output table by modifying this line of code:

assignmentTable(endTime,{'TrackID','AssignedTruthID','TotalLength','DivergenceCount','RedundancyCount','RedundancyLength','truthMetrics','trackMetrics'})

This is further elaborated in the following example:
