i have the following problem:
i have two functions: f[Q] and x[Q] and i want f[x]. i cant invert
x[Q], so i do this like this:
fx=Interpolation[Table[{x[Q],f[Q]},{Q,0,10,0.1}]]
this work fine.
but now my function depends on 2 variables: f[Q,R] with given x[Q] and
y[R]. How can i now interpolate the function f[x,y]?
(I tried 'ListInterpolation' but couldnt find a solution)
any help appreciated.
