[Insight-users] How to calculate AUC (Area under a curve)

[Gianna Nigro]

Hello,
I would like to ask if there is a way to calculate the area under a curve,
having a set of values for x and y coordinates: I've got 2 vectors, with
same number of elements, one containing x values and the other containing y
values. I'm searching for something that computes the area under the curve
obtained interpolating these coordinates, if it does exist.

Thanks to all,
Gianna
