NewtonRaphsonFindRootNearGuess Method

public static double FindRootNearGuess(
	Func<double, double> f,
	Func<double, double> df,
	double initialGuess,
	double lowerBound = -1,79769313486232E+308,
	double upperBound = 1,79769313486232E+308,
	double accuracy = 1E-08,
	int maxIterations = 100
)

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  (Optional)

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

upperBound  Double  (Optional)

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

accuracy  Double  (Optional)

Desired accuracy. The root will be refined until the accuracy or the maximum number of iterations is reached. Default 1e-8. Must be greater than 0.

maxIterations  Int32  (Optional)

Maximum number of iterations. Default 100.
