Dear all,
I need to perform a numerical integration (2-Dim) over the interpolated function of four (4!) variables.
(\int dx dy Interpolation{F(x,y,z,w)})
The similar procedure exists in ROOT: by using ROOT::Math::Interpolator with “Integ” option. But it is done only for 1-Dim function (a function of only one variable).
My question: Is there in ROOT a multivariate interpolation (over the 4 Dim ) with the “Integ” option (2Dim integration)?
Thank you!
A.K.
