I'm not very familiar with geometrical analysis. Therefore I'm asking the community for some help. Here is my problem. I have different amounts of points in every experiment, but at least 3. From these points i need the area. For 3 points there are no problems, this is just a triangle ( the calculation isn't very difficult). But if I get more points I don't no how automize the calculation of the area. Till now I'm doing triangulation manually.
Maybe there is a build-in function in matlab that I don't know.
