GearsBDFWithNordsieckStateInitialize(Double, Double, ActionDouble, Double, Double, MultiStepMethodBaseCalculateJacobian) Method

This initialization method is intended for debugging and testing purposes only, because you will need the derivatives up to order k at the initial point.

Namespace: Altaxo.Calc.Ode
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3448.0 (4.8.3448.0)

Syntax

Copy

public GearsBDFWithNordsieckState Initialize(
	double x0,
	double[][] initDerivatives,
	Action<double, double[], double[]> f,
	MultiStepMethodBaseCalculateJacobian jacobianEvaluation

Parameters

x0 Double: The starting value of the independent variable x.
initDerivatives Double: The starting values of the 0th .. k-th derivatives of y, i.e. y, dy/dx, d2y/dx2, etc.
f ActionDouble, Double, Double: The function used to evaluate the first derivatives dy/dx.
jacobianEvaluation MultiStepMethodBaseCalculateJacobian: The function used to evaluate the Jacobian.

Return Value

GearsBDFWithNordsieckState
