Parameters

[in]	field	The input field on (nx,ny,nz)
[in,out]	scheme	The scheme that you want to use
[in]	axis	\({1,2,3}\) is the axis \(x\), \(y\) or \(z\) along which to extrapolate
[in]	index	The starting/ending index of the cells
[in]	neumann_value	The input Neumann boundary values (spatial_dimension-1) field of type type_bc_value, where the Neumann condition is imposed on the face
[out]	extrapolated_value	The resulting extrapolated values
