In particular, pkg/profiles can be used to do model-data etc., and it contains model mask variables (e.g. the computed offline using netcdf_ecco_GenericgridMain.m. code in combination with the tutorial_global_oce_optim Time varying weights can be cold start, followed by one or several iterations of optimization, warm start from previous cold start with one or several iterations, warm start from previous warm start with one or several iterations.
