What's the algorithm for finding scalar function satisfying div f=F if I know vector F?

There isn't one. div is not defined on scalars and the divergence of a vector would be a scalar. What did you really mean to ask?

Sorry, I meant grad f=F, and I want to get scalar function f from vector F (for instance electric potential from electric intensity).
