subroutine | t_rec_fast_scheme_houc3_backward_compute_weights (stencil, nx, dx, shift, preweights) |
| Compute the weights associated to the scheme at each cell in [1:nx].

subroutine | t_rec_fast_scheme_houc3_forward_compute_weights (stencil, nx, dx, shift, preweights) |
| Compute the weights associated to the scheme at each cell in [1:nx].

double precision function | t_rec_fast_scheme_houc3_apply_fast (self, values, preweights) |
| Apply the corresponding scheme.

type(t_rec_fast_scheme_houc3_backward), target | rec_fast_scheme_houc3_backward |

- Note
- The fixed position is at the end of the 0's cell (for forward). This is the usual position for reconstruction schemes.

- Warning
- as we cannot access to values outside [1:nx], the weights are in fact computed in the computable stencil around the cell.
