org.apache.commons.math.analysis.BisectionSolver
- All Implemented Interfaces:
- Serializable, UnivariateRealSolver
- public class BisectionSolver
- extends UnivariateRealSolverImpl
Implements the
bisection algorithm for finding zeros of univariate real functions.
The function should be continuous but not necessarily smooth.

BisectionSolver
public BisectionSolver(UnivariateRealFunction f)
- Construct a solver for the given function.
- Parameters:
f - function to solve.
solve
public double solve(double min,
double max,
double initial)
throws ConvergenceException,
FunctionEvaluationException
- Find a zero in the given interval.
- Parameters:
min - the lower bound for the interval.max - the upper bound for the interval.initial - the start value to use (ignored).
- Returns:
- the value where the function is zero
- Throws:
ConvergenceException - the maximum iteration count is exceeded
FunctionEvaluationException - if an error occurs evaluating
the function
IllegalArgumentException - if min is not less than max
