NonlinearCurve.FillPartialDerivatives Method

Fills a dense vector with the partial derivatives of the curve with respect to each of the curve parameters.

Definition

Namespace: Extreme.Mathematics.Curves
Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
C#
public virtual void FillPartialDerivatives(
	double x,
	DenseVector<double> derivatives
)

Parameters

x  Double
The value at which the partial derivatives should be evaluated.
derivatives  DenseVector<Double>
A dense vector that is to hold the partial derivatives. The length of this vector must be at least the number of parameters of the curve.

Remarks

This method calculates the partial derivatives at the specified point with respect to the parameters of the curve. The current values of the parameters are used.

The default implementation of this method calculates the partial derivatives using simple forward differences.

Exceptions

ArgumentNullExceptionderivatives is null.
