BrentFindRootExpand Method

public static double FindRootExpand(
	Func<double, double> f,
	double guessLowerBound,
	double guessUpperBound,
	double accuracy = 1E-08,
	int maxIterations = 100,
	double expandFactor = 1,6,
	int maxExpandIteratons = 100
)

Parameters

f  FuncDouble, Double

The function to find roots from.

guessLowerBound  Double

Guess for the low value of the range where the root is supposed to be. Will be expanded if needed.

guessUpperBound  Double

Guess for the high value of the range where the root is supposed to be. Will be expanded if needed.

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.

expandFactor  Double  (Optional)

Factor at which to expand the bounds, if needed. Default 1.6.

maxExpandIteratons  Int32  (Optional)

Maximum number of expand iterations. Default 100.
