| BrentSolver | | public class BrentSolver extends UnivariateRealSolverImpl (Code) | | Implements the
Brent algorithm for finding zeros of real univariate functions.
The function should be continuous but not necessarily smooth.

| Method Summary | |
| public double | solve(double min, double max, double initial)
Find a zero in the given interval.
Throws ConvergenceException if the values of the function
at the endpoints of the interval have the same sign.
Parameters:
min - the lower bound for the interval.
Parameters:
max - the upper bound for the interval.
Parameters:
initial - the start value to use (ignored). | | public double | solve(double min, double max)
Find a zero in the given interval.
Requires that the values of the function at the endpoints have opposite
signs. |
| solve | | public double solve(double min, double max, double initial) throws ConvergenceException, FunctionEvaluationException(Code) | | Find a zero in the given interval.
Throws ConvergenceException if the values of the function
at the endpoints of the interval have the same sign.
Parameters:
min - the lower bound for the interval.
Parameters:
max - the upper bound for the interval.
Parameters:
initial - the start value to use (ignored). the value where the function is zero
throws:
ConvergenceException - the maximum iteration count is exceeded
throws:
FunctionEvaluationException - if an error occurs evaluatingthe function
throws:
IllegalArgumentException - if initial is not between min and max |
| solve | | public double solve(double min, double max) throws ConvergenceException, FunctionEvaluationException(Code) | | Find a zero in the given interval.
Requires that the values of the function at the endpoints have opposite
signs. An IllegalArgumentException is thrown if this is not
the case.
Parameters:
min - the lower bound for the interval.
Parameters:
max - the upper bound for the interval. the value where the function is zero
throws:
ConvergenceException - if the maximum iteration count is exceeded
throws:
FunctionEvaluationException - if an error occurs evaluating thefunction
throws:
IllegalArgumentException - if min is not less than max or thesigns of the values of the function at the endpoints are not opposites |
