 #1 Posted on 12.11.04 1255.09 Reposted on: 12.11.11 1255.13   Not sure if this goes here or in Random, or if anyone on this board could even help me with this, but here goes.
I'm looking for a numerical integration technique, which can be implemented in either Matlab or Maple, which can give me the area of a shape of rather complex geometry, defined by a set of discrete points. I've got ways of doing a rough approximation of this (ie the polyarea function in Matlab) but am considerably lost as to how to do this with a higher degree of precision. I am able to create a cubic spline for the shape, and I believe this may help, but again I don't know the techniques of integration which would lead me to my answer.
As this probably wouldn't lead to much of a group discussion, replies by PM would be appreciated. Unless, of course, there are more mathematicians on this board than I thought.  Promote this thread!   ALL ORIGINAL POSTS IN THIS THREAD ARE NOW AVAILABLE
