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.

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 heimbach 1.3 c release output. The off-line version can, of course, only
33 heimbach 1.2 c do one optimization step at a time.
