Hello everyone,

I have a function which I read as a list of points. I want then to
estimate its integral. I do more or less this :

data={{x1,y1},{x2,y2},...,{xN,yN}}
f=Interpolation[data]
NIntegrate[f[x],{x,x1,xN}]

Is it the correct way ? Because Mathematica hangs without giving me an
answer although it seems a pretty straightforward thing to do...

Thanks for any suggestions.
