Is there any function available for 3d point clouds to do control point registration?

Control point registration is available for 2d images in matlab (Control Point Registration - MATLAB & Simulink - MathWorks India). I want to do that registration for 3d point clouds by selecting four pairs of corresponding points from moving and reference point cloud. How to do that?
