gsl has an excellent manual.
All of this is covered, with examples, at
https://www.gnu.org/software/gsl/manual/html_node/Initializing-the-Solver.html#Initializing-the-Solver
https://www.gnu.org/software/gsl/manual/html_node/Root-Bracketing-Algorithms.html#Root-Bracketing-Algorithms
This is root_fsolver not the multifit_fsolver !!!
Whoops.
Well, the same stands for multifit_fsolver: documentation exists in the
manual.
https://www.gnu.org/software/gsl/manual/html_node/Minimization-Algorithms-without-Derivatives.html#Minimization-Algorithms-without-Derivatives
So it seems gsl doesn't have anything implemented currently. You can
always use finite difference derivatives though...
