10 c ==================================================================
11 c
12 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.
22 c
23 c
24 c Documentation:
25 c
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.
