I have a set of (x,y) coordinates that, when connected, create an ellipse-like shape on my plot. How can I find the area enclosed within my curve?

One option is to use the "polyarea" function,

where each point is interpreted as a vertex on a polygon. A straight line connects each point, but if you include enough points, your shape will begin to approximate a curve, and your area calculation will be more accurate.
