When I try to run this example openExample('shared_driving_fusion_lidar/DetectClassifyAndTrackOrientedBoundingBoxInLidarExample'),
it is giving "Unrecognized field name "ptCloudData"". Though I have required toolboxes.
Please help to fix this problem.

Have you used the supporting function to download the supporting data?
The first line of the example is:
[ptClouds,pretrainedModel] = helperDownloadData;

Thank you it fixed the problem. However if I use like below, still it is giving the same error.
% First way
dataFile = 'lidarData_1.mat';
data = load(dataFile);
ptClouds = data.ptCloudData;
ptCloud = ptClouds{1};
% ----------------------
% as per the documentation even if use like this still it is giving error
% Second way
[ptClouds] = helperDownloadData;
ptCloud = ptClouds{1};
function [lidarData] = helperDownloadData
dataFile = 'lidarData_1.mat';
data1 = load(dataFile);
lidarData = data1.ptCloudData;
