FunctionBasis at a specified value.
Definition
Namespace: Numerics.NET.Curves
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3
C#
A vector containing the derivatives of the member functions.
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.3
public DenseVector<double> DerivativesAt(
double x
)
Parameters
- x Double
- A real number.
Return Value
DenseVector<Double>A vector containing the derivatives of the member functions.
Remarks
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.
