NewtonRaphsonTryFindRoot Method

public static bool TryFindRoot(
	Func<double, double> f,
	Func<double, double> df,
	double initialGuess,
	double lowerBound,
	double upperBound,
	double accuracy,
	int maxIterations,
	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.

initialGuess  Double

Initial guess of the root.

lowerBound  Double

The low value of the range where the root is supposed to be. Aborts if it leaves the interval.

upperBound  Double

The high value of the range where the root is supposed to be. Aborts if it leaves the interval.

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.

root  Double

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