I have a list of points like
I ploted this list with ListPlot[A]
now I want to know the surface of what I ploted.
I have a hysteresis loop and in order to recieve the permability I need to know how big is the included area within the loop.
Is there a function to integrate something like this in mathematica, if I don't have a funcion f(x) but just a plot?
I was looking through the help of mathematica, the student support here and internet, but I couldn't find anything.
