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 output. The off-line version can, of course, only |
33 |
c do one optimization step at a time. |
