    Open Live Script

    Download a ZIP file containing an E57 file, and then unzip the file. 

    zipFile = matlab.internal.examples.downloadSupportFile("lidar","data/e57ParkingLot.zip");
saveFolder = fileparts(zipFile);
e57FileName = [saveFolder filesep 'parkingLot.e57'];
if ~exist(e57FileName,"file")
    unzip(zipFile,saveFolder)
end

    Create an e57FileReader object.

    e57Reader = e57FileReader(e57FileName);

    Inspect the values of the NumPointClouds and PointCloudIndex properties of the e57Reader object.

    disp(e57Reader.NumPointClouds);
        19

    disp(e57Reader.PointCloudIndex);
         1

    Read the last point cloud from the E57 file and verify that the readPointCloud object function advances the PointCloudIndex property to the next value after NumPointClouds.

    ptCloud = readPointCloud(e57Reader,e57Reader.NumPointClouds);
disp(e57Reader.PointCloudIndex);
        20

    Reset the e57FileReader object and verify that the value of the PointCloudIndex property is reset to 1.

    reset(e57Reader);
disp(e57Reader.PointCloudIndex);
         1
