SymbolicMath.GetValueAndDerivative Method

public static FunctionWithDerivative GetValueAndDerivative(
	Expression<Func<double, double>> targetFunction
)

Public Shared Function GetValueAndDerivative ( 
	targetFunction As Expression(Of Func(Of Double, Double))
) As FunctionWithDerivative

public:
static FunctionWithDerivative^ GetValueAndDerivative(
	Expression<Func<double, double>^>^ targetFunction
)

static member GetValueAndDerivative : 
        targetFunction : Expression<Func<float, float>> -> FunctionWithDerivative 

Parameters

targetFunction  Expression<Func<Double, Double>>

A lambda expression that represents a function of one variable.

Return Value

The derivative is calculated symbolically from the supplied lambda expression. The expression must not contain loops or blocks. If functions are encountered for which no symbolic derivative is available, a numerical approximation is used.
