You might be interested in the geodist function in
http://www.mathworks.com/matlabcentral/fileexchange/39108. This offers the same functionality as vdist without the convergence problems of Vincenty's algorithm.

13 Jan 2014 Geodesic projections for an ellipsoid Four map projections based on geodesics Author: Charles Karney Manley-Cooke, Peter

After downloading the earlier submission by this author (as indicated at the bottom of the description), this program provides instant answers. Well Done.

Line one of the Description should contain the information that the mapping toolbox is required for this submission.

This... is absolutely wonderful. I spent ages looking for a toolbox that would calculate geodesic areas. I figured that my only two options would be to purchase the MATLAB mapping toolbox or write a routine myself. I'm so glad I finally found this. Thank you kindly, sir.
