c optim.F: Routines for doing an off-line optimization after the |
| 13 |
c ECCO forward and adjoint model have been run. |
| 14 |
c |
| 15 |
c numbmod - Returns number of variables. |
| 16 |
c simul - Mid-level routine that calls the model and its |
| 17 |
c adjoint |
| 18 |
c model - Forward model. |
| 19 |
c admodel - Modified forward model and adjoint model. |
| 20 |
c initmod - Initialisation routine. |
| 21 |
c postmod - Final routine that prints results. |

| 26 |
c The collection of these routines originated mainly from Ralf |
| 27 |
c Giering. Patrick Heimbach improved and corrected some parts of |
| 28 |
c the original code. Christian Eckert contributed the interface |
| 29 |
c to the ECCO release of the MITgcmUV in order to get the off- |
| 30 |
c line version going. The on-line optimisation uses a simple |
| 31 |
c example, whereas the off-line version deals with the ECCO |
| 32 |
c release's output. The off-line version can, of course, only |
| 33 |
c do one optimization step at a time. |
