Unrecognized function or variable 'helperGetDataset'.

When I run the code:

lidarData = helperGetDataset;

It gives me this error:

Unrecognized function or variable 'helperGetDataset'.

Error in LANE (line 1)

lidarData = helperGetDataset;

That appears to refer to https://www.mathworks.com/help/lidar/ug/lane-detection-in-3d-lidar-point-cloud.html

To confirm: do you have the lidar toolbox installed?

Yes I do

Did you open the example using the following command?

openExample('lidar/LaneDetectionOnLidarPointCloudExample')
