Minimizes a function in the vicinity of a given point.

Namespace:  Meta.Numerics.Functions
Assembly:  Meta.Numerics (in Meta.Numerics.dll) Version: 1.5.0.0 (1.5.0.0)

Syntax

         
 C#  Visual Basic  Visual C++ 
public static LineExtremum FindMinimum(
	Function<double, double> f,
	double x
)
Public Shared Function FindMinimum ( _
	f As Function(Of Double, Double), _
	x As Double _
) As LineExtremum
public:
static LineExtremum^ FindMinimum(
	Function<double, double>^ f, 
	double x
)

Parameters

f
Function<(Of <(Double, Double>)>)
The function.
x
Double
A point suspected to be near the minimum; the search begins at this point.

Return Value

The minimum.

Remarks

Since the search algorithm begins by evaluating f near x, it can fail if x is near a singularity or other point at which the evaluation of f could fail. If you can reliably bracket a minimum, the other overload of this method is safer and, if your bracket is any good, slightly faster.

Exceptions

ExceptionCondition
System..::.ArgumentNullException f is null.
