RobustNewtonRaphsonTryFindRoot Method

public static bool TryFindRoot(
	Func<double, double> f,
	Func<double, double> df,
	double lowerBound,
	double upperBound,
	double accuracy,
	int maxIterations,
	int subdivision,
	out double root
)

Parameters

f  FuncDouble, Double

The function to find roots from.

df  FuncDouble, Double

The first derivative of the function to find roots from.

lowerBound  Double

The low value of the range where the root is supposed to be (finite number).

upperBound  Double

The high value of the range where the root is supposed to be (finite number).

accuracy  Double

Desired accuracy. The root will be refined until the accuracy or the maximum number of iterations is reached. Example: 1e-14. Must be greater than 0.

maxIterations  Int32

Maximum number of iterations. Example: 100.

subdivision  Int32

How many parts an interval should be split into for zero crossing scanning in case of lacking bracketing. Example: 20.

root  Double

The root that was found, if any. Undefined if the function returns false.
