Geometry library for matlab. Performs geometric computations on points, lines, circles, polygons...
function rev = reversePolygon(poly)
%REVERSEPOLYGON Reverse a polygon, by iterating vertices from the end
% POLY2 = reversePolygon(POLY)
% POLY2 has same vertices as POLY, but in different order. The first
% vertex of the polygon is still the same.
