You can preview your Velodyne LiDAR® point clouds before acquiring the data.

Create a velodynelidar object, v, for use with a model HDL-32E sensor. 

v = velodynelidar('HDL32E');

Preview the point cloud data.

preview(v);

The preview window opens.

Note that you must close the preview window before you can use the read function to acquire data.
