NewtonRaphsonRootFinderFind(OneVariableFunction, OneVariableFunction, Double, Double) Method

Finds a root within the interval.

Namespace: CenterSpace.NMath.Core
Assembly: NMath (in NMath.dll) Version: 7.4

Syntax

public double Find(
	OneVariableFunction f,
	OneVariableFunction df,
	double lower,
	double upper
)

Public Function Find ( 
	f As OneVariableFunction,
	df As OneVariableFunction,
	lower As Double,
	upper As Double
) As Double

public:
virtual double Find(
	OneVariableFunction^ f, 
	OneVariableFunction^ df, 
	double lower, 
	double upper
) sealed

abstract Find : 
        f : OneVariableFunction * 
        df : OneVariableFunction * 
        lower : float * 
        upper : float -> float 
override Find : 
        f : OneVariableFunction * 
        df : OneVariableFunction * 
        lower : float * 
        upper : float -> float

Parameters

f OneVariableFunction: The function.
df OneVariableFunction: The derivative of f.
lower Double: The lower limit.
upper Double: The upper limit.

Return Value

Double
A root of f within the interval between lower and upper.

Implements

IOneVariableDRootFinderFind(OneVariableFunction, OneVariableFunction, Double, Double)

Exceptions

Exception	Condition
NMathException	Thrown if a root is not found.

Remarks

Iteration stops when either the estimated error is less than the tolerance, or the maximum number of iterations is reached. Setting the error tolerance to less than zero ensures that the maximum number of iterations is always reached.
