) As Double
public:
[ExtensionAttribute]
static double FindZero(
Func<double, double>^ targetFunction,
double initialGuess
)
[<ExtensionAttribute>]
static member FindZero :
targetFunction : Func<float, float> *
initialGuess : float -> float
Parameters
- targetFunction
- Type: SystemFuncDouble, Double
A delegate that represents a function of one variable that specifies the function on the left-hand
side of the equation. - initialGuess
- Type: SystemDouble
An initial guess for ther zero.
Return Value
Type:
DoubleThe best approximation to a zero of
targetFunction.
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
FuncDouble,
Double. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
Use this method when you have very little information about the location of the zero.
