Function Documentation

getFornbergStencilCoefficients()

Vector<Real> getFornbergStencilCoefficients	(	const int	n_order,
		const bool	nodal
	)

Returns an array of coefficients (Fornberg coefficients), corresponding to the weight of each point in a finite-difference approximation of a derivative (up to order n_order).

Parameters

[in]	n_order	order of the finite-difference approximation
[in]	nodal	whether the finite-difference approximation is computed on a nodal grid or a staggered grid
