Whoops.

Well, the same stands for multifit_fsolver: documentation exists in the

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...
