BisectionSolver
Deprecated.as of 2.0 the function to solve is passed as an argument to thesolve(UnivariateRealFunction, double, double)
orUnivariateRealSolver.solve(UnivariateRealFunction, double, double, double)
method.Construct a solver for the given function.- Parameters:
f
- function to solve.

solve
@Deprecated public double solve(double min, double max, double initial) throws MaxIterationsExceededException, FunctionEvaluationException Deprecated.Solve for a zero in the given interval, start at startValue.A solver may require that the interval brackets a single zero root. Solvers that do require bracketing should be able to handle the case where one of the endpoints is itself a root.
- Parameters:
min
- the lower bound for the interval.max
- the upper bound for the interval.initial
- the start value to use- Returns:
- a value where the function is zero
- Throws:
FunctionEvaluationException
- if an error occurs evaluating the functionMaxIterationsExceededException
-

- Parameters:
min
- the lower bound for the interval.max
- the upper bound for the interval.- Returns:
- a value where the function is zero
- Throws:
