> Hello.
> I was wondering why all the root finders (e.g. NewtonSolver, BrentSolver, etc.) require the function to be passed as an argument to the contructor.
> It should be possible to pass it when calling the method "solve" i.e.      
>    double solve(UnivariateRealFunction f, double min, double max)
> This would be much more flexible, e.g. allowing one to use the same solver instance for several functions.
>                                                                                 
> For example, my need would be something like the following (currently impossible) code:
>       public class Zero implements UnivariateRealFunction {
>           public value(double x) throws FunctionEvaluationException {    
>               return ...;
>          }
>          public double get(UnivariateRealSolver s, double min, double max) {
>              return s.solve(this, min, max);
>          }
>       }
> Best regards,
> Gilles
