I have a n by 3 single array. As I want to plot just the x and y data, I need to delete the z column in that array. Could you please tell me how that is done?
Thanks in advance!

You do not have just an array of points. You have one pointCloud object, which contains an array of x,y,z coordinates in the Location property. So you can do this:
array = ptCloud.Location(:, 1:2);

Thank you this works, but in the array there are 480 x and y values now. Before there have been 80 000. Do you know why?

array = array(:,1:2);
array(:,3) = [];
