I plot point cloud figure in MATLAB using Kinect-V2 camera. I determined three markers in the MATLAB figure using the Data cursor tool to get the (x,y,z) of these points. Then, I saved these data as a (.mat file). When I open it again, I found that MATLAB saves the data of each marker in a structure array.

How can I get again (x,y,z) of these markers from the Structure arrays?

Attached to the message the structure arrays of the 3-point cloud.
