I have a point cloud and I first draw surface of these points using matlab(by centering of points). my points have 3D coordinates including (X,Y,Z). original of points are same:
32512035.2100000 5401399.57000000 346.880000000000
32512044.0300000 5401399.54000000 346.850000000000
32512046.8900000 5401399.55000000 346.780000000000
32512049.7800000 5401399.53000000 346.860000000000
32512052.6900000 5401399.53000000 346.700000000000
32512054.0300000 5401399.53000000 346.780000000000
32512055.6900000 5401399.57000000 346.810000000000
32512063.1200000 5401399.54000000 347.800000000000
32512074.2300000 5401399.55000000 346.440000000000
32512093.1200000 5401399.54000000 346.660000000000
and centering of them are:

-19.9091900000931 -4.00948997773230 -0.730859999999382

29.1808099997579 -4.00948997773230 -0.920859999999379
and I draw surface using fit
formula in matlab.
I want to calculate curvature of each point and try here and here but I can't understand "The inputs (X,Y,Z) are 2D arrays corresponding to the surface being analyzed." thing. anybody to help me? or tell to me that how can I calculate curvature?
