diff_y_p() double pism::array::diff_y_p ( const array::Scalar &  array, int  i, int  j  ) Returns the y-derivative at i,j approximated using centered finite differences. Respects grid periodicity and uses one-sided FD at grid edges if necessary. Definition at line 129 of file Scalar.cc. References diff_y(), pism::array::Array::grid(), and pism::grid::Y_PERIODIC.
