Public Function DerivativesAt (

) As DenseVector(Of Double)

C++/CLI

member DerivativesAt : 
        x : float -> DenseVector<float>

DenseVector<Double>
A vector containing the derivatives of the member functions.

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

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