GSLLevenbergMarquardtMinimizer Class Reference
It's a facade to ROOT::Math::GSLNLSMinimizer which, in turn, is a facade to the actual GSL's gsl_multifit_fdfsolver_type (http://www.gnu.org/software/gsl/manual/html_node/Nonlinear-Least_002dSquares-Fitting.html). More...

Detailed Description
It's a facade to ROOT::Math::GSLNLSMinimizer which, in turn, is a facade to the actual GSL's gsl_multifit_fdfsolver_type (http://www.gnu.org/software/gsl/manual/html_node/Nonlinear-Least_002dSquares-Fitting.html).

Member Function Documentation
◆ setMaxIterations()
| void GSLLevenbergMarquardtMinimizer::setMaxIterations | ( | int | value | ) |
Sets maximum number of iterations.
This is an internal minimizer setting which has no direct relation to the number of objective function calls (e.g. numberOfIteraction=5 might correspond to ~100 objective function calls).
