I don't have access to v2009, so DelaunayTri is out (http://www.mathworks.com/products/demos/shipping/matlab/demoDelaunayTri.html#19)

I have several ellipses defined by a point cloud, and I can separate them and take them into account one at a time. Some are regular ellipses, some are curved
(googleimages example: http://www.mmm.ucar.edu/mm5/documents/MM5_tut_Web_notes/OA/OA-4.gif). I have a collection of points for each.

The end goal is to find the area of each ellipse, but without being able to follow the example I linked at the top, I'm not sure how to find the concave polygon that fits the ellipse. I know that for an arbitrary shape, this is an ill-posed problem, but if I know that each shape is a curved ellipse, does that help me at all?

Forgot to mention that my points are all border points, not interior points.
