FunctionBasis<T>.DerivativesAt Method

public DenseVector<T> DerivativesAt(
	T x
)

Public Function DerivativesAt ( 
	x As T
) As DenseVector(Of T)

public:
DenseVector<T>^ DerivativesAt(
	T x
)

member DerivativesAt : 
        x : 'T -> DenseVector<'T> 

Parameters

x  T

A real number.

Return Value

This method creates a new Vector every time it is called. In some situations, it may be more efficient to call the FillDerivatives(T, DenseVector<T>) method instead.

If no derivative functions have been defined for the member functions, the derivatives are approximated numerically.
