Parameters

	field	The field defined on the cells
[in,out]	scheme	the finite difference scheme: forward (resp. backward) for backward (resp. forward) extrapolation
[in]	i,j,k	The index of the cell
[in]	axis	The axis (direction) {1,2,3} for {u,v,w}
[in]	derivative_value	The value of the derivative at the extrapolation point

Returns

The extrapolation of field from the cell i,j,k along the given axis to the point indicated by its distance to the cell with the given Neumann condition.
