Syntax

public abstract class AbstractRootFinder

The AbstractRootFinder type exposes the following members.

Constructors

	Name	Description
	AbstractRootFinder(FuncDouble, Double)	Initializes a new instance of the AbstractRootFinder class.
	AbstractRootFinder(FuncDouble, Double, Int32, Double)	Initializes a new instance of the AbstractRootFinder class.

Properties

	Name	Description
	Accuracy	Gets or sets the desired accuracy for the computed root.
	BracketingFactor	Gets or sets the factor used for outward bracketing when searching for an interval that contains a root.
	MaximumNumberOfIterations	Sets the maximum number of iterations.
	MessageAccuracyNotReached	Gets the localized error message used when the requested accuracy cannot be reached within the maximum number of iterations.
	MessageInadequateAlgorithm	Gets the localized error message used when the chosen algorithm cannot solve the equation.
	MessageInvalidRange	Gets the localized error message used when an invalid range is encountered while finding a root.
	MessageRangeArgumentInvalid	Gets the localized error message used when the provided range argument is not valid.
	MessageRootNotBracketed	Gets the localized error message used when the algorithm cannot start because the root does not seem to be bracketed.
	MessageRootNotFound	Gets the localized error message used when the algorithm ends without finding a root in the range.

Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	Find	Performs the algorithm-specific root search on the currently configured interval.
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	SearchBracketsOutward	Detects a range containing at least one root.
	Sign	Helper method useful for preventing rounding errors.
	Solve(Double, Double, Boolean)	Solves the equation f(x) == 0.
	Solve(Double, Double, Double, Boolean)	Solves the equation f(x) == y.
	Swap	Swaps the values of two Double variables.
	ToString	Returns a string that represents the current object. (Inherited from Object)

Fields

	Name	Description
	_accuracy	Desired accuracy for the computed root.
	_function	Function for which a root should be found.
	_maximumNumberOfIterations	Maximum number of iterations used by the algorithm.
	_originalFunction	Stores the original function when the solver is temporarily configured to solve f(x) == y.
	_xMax	Upper bound of the current search interval.
	_xMin	Lower bound of the current search interval.
	double_Accuracy	Machine epsilon-like accuracy threshold, used as an internal constant.
