C#
public static double FindZero(
	Func<double, double> function,
	double lowerBound,
	double upperBound,
	double tolerance = 1.49011611938477E-08,
	int maxIterations = 200,
	double rightHandSide = 0
)

Parameters

function  Func<Double, Double>
The function to find the zero for.
lowerBound  Double
The lower bound of the interval.
upperBound  Double
The upper bound of the interval.
tolerance  Double  (Optional)
Optional. The tolerance for the zero finding. The default is SqrtEpsilon
maxIterations  Int32  (Optional)
Optional. The maximum number of iterations. The default is 200.
rightHandSide  Double  (Optional)
Optional. A value to subtract from the result of function. The default is 0.

Return Value

Double
The value where function equals rightHandSide.

Exceptions

ArgumentExceptionThrown if the values of function at lowerBound and upperBound have the same sign.
ConvergenceExceptionThrown if the algorithm fails to converge.
