Trying to familiarise myself with the radar functions, specifically the "Tracking Using Bistatic Range Detections" examples.
I keep getting errors related to some of the helper functions involved. Specifically, "helperBistaticRangeFusionDisplay is not defined for class 'helperBistaticRangeFusionDisplay' or is removed from MATLAB's search path." and (I believe subsequently) "Update traversal encountered invalid scene tree"
Is there some functionality here that's been removed? Or am I missing somthing.
Thanks very much.
Andre

Hi Andre,
If you open this example using the link in the doc (which translates to this MATLAB command):
openExample('fusion/TrackingUsingBistaticRangeDetectionsExample')
You should find these helper functions in the current working directory.
Thanks,
Prashant

Unfortunately it throws errors there too.
I am using a 3060 Ti, gpu, could this be causing my issues?
Error in fusion.theaterPlot.PlatformPlotter/plotPlatform (line 276)
drawnow limitrate;
Error in helperBistaticRangeFusionDisplay/plotPlatforms (line 810)
plotPlatform(obj.pPlatformPlotters(m),pos(idx,:)/obj.pScale,vel(idx,:)/obj.pScale);
Error in helperBistaticRangeFusionDisplay/stepImpl (line 387)
plotPlatforms(obj,truths);
Error in TrackingUsingBistaticRangeDetectionsExample (line 368)
theaterDisplay([superDets(:);detections(:)],confTracks);
Update traversal encountered invalid scene tree.

I have reset my matlab instance and this code appears to be working. I may have inadvertantly changed a setting while I was working early. Apologies for the mishap. I wish I could be of more help to indicate what had happened to make this initial case malfunction, but I unfortunately cannot.
Thank you again,
Andre.
