org.apache.commons.math.analysis.UnivariateRealSolver.solve()
Solve for a zero root in the given interval. A solver may require that the interval brackets a single zero root. @param min the lower bound for the interval. @param max the upper bound for the interval. @return a value where the function is zero @throws ConvergenceException if the maximum iteration count is exceededor the solver detects convergence problems otherwise. @throws FunctionEvaluationException if an error occurs evaluating thefunction @throws IllegalArgumentException if min > max or the endpoints do notsatisfy the requirements specified by the solver
