%
%  computes estimation and physical diagnostics (setDiags) that 
%  can be included in the standard analysis from the data (for 
%  selected years) located in dirModel and stores the results 
%  in dirMat.
%
%notes: dirModel is the directory containing 'diags/' or 'nctiles/'
%       dirMat is [dirModel 'mat/'] by default
%       years may be set to a vector (e.g. [1992:2011]) or to
%          'climatology' when using a climatological year
%       setDiags is by default set to {'A','B','C','MLD'}
%       doInteractive=1 allows users to specify parameters interactively
%          whereas doInteractive = 0 (default) uses ECCO v4 parameters
