trackingHistStruct = struct('tid', 0, 'allocationTime', 0, 'tick', 0, 'posIndex', 0, 'histIndex', 0, 'sHat', zeros(1000,6), 'ec', zeros(1000,9),'pos', zeros(100,2), 'hMeshU', [], 'hMeshG', [], 'hPlotAssociatedPoints', [], 'hPlotTrack', [], 'hPlotCentroid', []);
trackingHist = repmat(trackingHistStruct, 1, maxNumTracks);
1.can you give me the explanation of the 'trackingHist''?
