class ROOT::Math::GSLRootFinder: public ROOT::Math::IRootFinderMethod


     Base class for GSL Root-Finding algorithms for one dimensional functions which do not use function derivatives.
     For finding the roots users should not use this class directly but instantiate the template
     ROOT::Math::RootFinder class with the corresponding algorithms.
     For example the ROOT::Math::RootFinder<ROOT::Math::Roots::Brent> for using the Brent algorithm. See that class also
     for the documentation.
     See the GSL <A HREF="http://www.gnu.org/software/gsl/manual/html_node/Root-Bracketing-Algorithms.html"> online manual</A> for
     information on the GSL Root-Finding algorithms
