NewtonRaphson Class

A class for finding zeros of a method, using the Newton-Raphson method

If the derivative is available, it can be provided, otherwise it works by numerically calculating the derivative.

Public Class NewtonRaphson

public ref class NewtonRaphson

The NewtonRaphson type exposes the following members.

Constructors

	Name	Description
	NewtonRaphson(NewtonRaphsonFunction)	Constructor for finding zeros of the function
	NewtonRaphson(NewtonRaphsonFunction, NewtonRaphsonFunction)	Constructor for finding zeros of the function

Properties

	Name	Description
	Derivative	Derivative of function to solve, if available, otherwise null.
	Epsilon	Epsilon, used in stopping criteria in the Newton-Raphson method. Default value is 1e-6 Both the Epsilon and the FEpsilon criteria must be met before the method is stopped
	FEpsilon	F-Epsilon, used in stopping criteria in the Newton-Raphson method. Default value is 1 (in most cases that is the same as disabling the criteria) Both the Epsilon and the FEpsilon criteria must be met before the method is stopped
	Func	Function to solve
	MaxIter	Maximum number of iterations. Default 100
	NewValueAction	Action to perform when a new value is calculated.
	NumIter	Hold the actual number of iterations for the last solve.

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.)
	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.)
	Solve	Solves for zeros, using x as starting point and updating the value of x as a result.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
