the function "helperPlo​tPositionE​rror"

I practice doing an example of radar simulation. During the implementation, I encountered the following error: "Index in position 2 exceeds array bounds. Index must not exceed 1".

The above error occurs when I use the function "helperPlotPositionError". The specific structure is as follows:

helperPlotPositionError(tgtPosTruth(:,:,1),time,tgtPosObs(:,firstTgtDet),detTime(firstTgtDet),scene.SimulationTime);

This is an example on the matlab website.

Can anyone help me answer, why is the above error and how to fix it?

Thank you

Which example? Please share a link to the doc page.

It sounds as if firstTgtDet exceeds 1 but tgtPosObs is something-by-1
