21  * placed in d_u.

24  * more general uses desire a single partial derivative of complex values, this
25  * should be moved to NumericalAlgorithms. This utility currently assumes the
26  * spatial dimensionality is 3, which would also need to be generalized, likely
27  * by creating a wrapping struct with partial template specializations.
