calculate the area of the surface formed by the points having coordinates [xd, yd]??
2 views (last 30 days)
first,i used 'polybool' to determine the overlap between plusieurs ellipses
[xd, yd] = polybool('intesection', x1, y1, x2, y2,'vector');
now i want to calculate the area of the surface formed by the points having coordinates [xd, yd],how can i do it??

you could do a Delauny Triangulation using the delaunay function and then calculate and sum up the area of each triangle. This should work as long your surface is one connected area. Or in the case the area of the convex hull is okay for your use polyarea.
