Syntax:
[totalArea, areas, centroid] = surfarea(x,y,z)
[totalArea, areas, centroid] = surfarea(h), where h is a handle to a Surface object.


surfarea calculates the total surface area as well as returns the areas of each individual cell, along with the area centroid of the surface.
Example: Plot peaks, coloring each cell with its own area.
[x,y,z] = peaks;
[area,cellAreas,centroid] = surfarea(x,y,z);

h = surf(x,y,z,cellAreas); axis image
title(sprintf('Total surface area: %.2f', surfarea(h)));
