How to remove unwanted points in point cloud

Hi,

I am a beginner to Matlab and would like some suggestion on how to remove the top point cloud (which is detached from the body) in the figure below

Thanks in advance

You can see that the unwanted points are lying in certain intervel of (x,y,z). Get those indices using logical indexing and remove them.

Example:

x = rand(1,100) ; 
x(x>0.5) = [] ;  % remove x which are greater than 0.5
