RationalCubicSplineSetBoundaryConditions Method

Sets the boundary conditions.

Namespace: Altaxo.Calc.Interpolation
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3572.0 (4.8.3572.0)

Syntax

public void SetBoundaryConditions(
	BoundaryConditions bnd,
	double b1,
	double b2
)

Parameters

bnd BoundaryConditions: The boundary condition. See remarks for the possible values.
b1 Double: The first boundary condition parameter.
b2 Double: The second boundary condition parameter.

Remarks


                  Natural
                      natural boundaries, that means the 2nd derivatives are zero
                      at both boundaries. This is the default value.
            
                  FiniteDifferences
                      use finite difference approximation for 1st derivatives.
            
                  Supply1stDerivative
                      user supplied values for 1st derivatives are given in b1 and b2
                      i.e. f'(x_lo) in b1
                           f'(x_hi) in b2
            
                  Supply2ndDerivative
                      user supplied values for 2nd derivatives are given in b1 and b2
                      i.e. f''(x_lo) in b1
                           f''(x_hi) in b2
            
                  Periodic
                      periodic boundary conditions for periodic curves or functions.
                      NOT YET IMPLEMENTED IN THIS VERSION.
