Copy
public double EvaluateDerivative(
	Func<double, double> f,
	double x,
	int order,
	double? currentValue = null
)

Parameters

f  FuncDouble, Double
Function handle.
x  Double
Point at which to compute the derivative.
order  Int32
Derivative order.
currentValue  NullableDouble  (Optional)
Current function value at center.

Return Value

Double
Function derivative at x of the specified order.
Remarks
Supplying the optional argument currentValue will reduce the number of function evaluations required to calculate the finite difference derivative.
