Is there an easy way to integrate a data set using the trapezoid rule, like the "trapz" function in matlab?
Also is there an easy way to find the centroid of this area?
I've attached a sample data set.

or I can add original "trapz" function to the matlab plugin if you really need this.

Ernesto,
Your data set is not impressive. As is: it represents no physical phenomenon.
The way I see it is otherwise ... it looks the linear junctions can only
represent derivatives of quadratic. It suggests a polynomial fit [offered].
Is it a piece of wood ? the fence around the yard ?

Thanks Ernesto, interesting.
You can complete and export your project,
