Subject: How to calculate area of enclosed loop? From: J K Date: 11 Apr, 2013 05:43:11 Message: 1 of 7 
I get data(x,y), and I plot it with Matlab. The graph is an enclosed loop. How to calculate the area?

It sounds that you are looking for Monte Carlo method?

> I assume when you say "an enclosed loop" you mean a closed curve in the xy plane  one that ends back at its start point. I believe there is a routine called "polyarea" which will do this but you can easily compute it yourself. Let x and y be vectors with cartesian coordinates that trace the points of the curve from beginning to end.
