interpolate_to_fine_grid()

template<int dim, int spacedim, typename VectorType >

void dealii::PolyUtils::internal::interpolate_to_fine_grid	(	const AgglomerationHandler< dim, spacedim > &	agglomeration_handler,
		VectorType &	dst,
		const VectorType &	src )

Same as the public free function with the same name, but storing explicitly the interpolation matrix and performing interpolation through matrix-vector product.
