trying:https://jp.mathworks.com/help/lidar/ug/detect-classify-and-track-vehicles-using-lidar.html
error:[ptClouds,pretrainedModel] = helperDownloadData;
→Unrecognized function or variable 'helperDownloadData'.
I have tried the following
・run openExample('shared_driving_fusion_lidar/DetectClassifyAndTrackOrientedBoundingBoxInLidarExample')

Hi Masa,
You are getting this error because MATLAB is not able to find the "helperDownloadData" function. You can remove this error by either creating a function file for this or adding the function definition at the end of your script; the function definitions of all the support functions are given at the end of the documentation page. For your reference, I'm attaching a direct link for the support functions mentioned in the documentation page. FYI I was able to run the example successsfully directly.
Hope this helps you to proceed with your workflow.
