Based on the example you referred to, the point cloud is an Object for storing a 3-D point cloud. For example the example uses this:
ptCloud = pointCloud(points3D, 'Color', color);
If you want to create a separate copy of a point cloud, you can use the MATLAB copy method. You can read more about this here under tips:
It does appear however, that you would like to save this data to use for further processing. For this, you can use the MATLAB "save" method that can be used to save specific variables to various file formats such as ".mat" or ".txt". For example, after the above line, you can use the following line to save the workspace variable to a mat file:
>> save('pointCloud.mat','ptCloud')

If you want to extract the xyz coordinates then
ptCloud.Location
will give them.
