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

Syntax

public double Find(
	OneVariableFunction f,
	double ax,
	double bx
)

Public Function Find ( 
	f As OneVariableFunction,
	ax As Double,
	bx As Double
) As Double

public:
virtual double Find(
	OneVariableFunction^ f, 
	double ax, 
	double bx
) sealed

abstract Find : 
        f : OneVariableFunction * 
        ax : float * 
        bx : float -> float 
override Find : 
        f : OneVariableFunction * 
        ax : float * 
        bx : float -> float

Parameters

f OneVariableFunction: The function.
ax Double: The lower bound.
bx Double: The upper bound.

Return Value

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

Implements

IOneVariableRootFinderFind(OneVariableFunction, Double, Double)

Exceptions

Exception	Condition
NMathException	The function evaluated at ax and bx must have different signs. FZero only finds bracketed single roots.

Remarks

Requires that the function evaluated at the two bounds be of opposite signs.

Copy

sign( f( lower )) != sign( f( upper ))
