Dear fluka experts,
        Firstly, thank Mr. Battistoni very much for help!
        I have more problems when sample a generic distribution. Now I
have numerically obtained the relation between
the uniform sample of (1,0) and self variable x, y, namely, F(x,y) =z
and 0<=z <1. I can obtain z by FLRNDM(DUMMY) function. Then
I want to obtain the x,y by inverse interpolation method to finish the
sample of f(x,y) . I want know if there is an inverse-interpolation
routine in the fluka .
Or can anyone give me some code and references? On the other hand,
please tell some details about interpolation function of yinter, finter,
d..intp in fluka. Is it possible to give me the math functions in
mathmvax folder?
       Thank you very much!
