==Introduction==

These pages describe a variety of Matlab scripts that can be used to pre-processing and post-processing ROMS data. Since all the data in ROMS is managed with NetCDF files, some of these scripts use a NetCDF interface to Matlab to process the data. There are several interfaces for Matlab available from third parties. The most widely used interface are '''MEXNC''' and '''SNCTOOLS'''.

{{note}} '''However''', starting Matlab version '''2012a''', released on Feb 9, 2012, the '''native''' interface to NetCDF is the preferred method for processing NetCDF data in the scripts distributed in the ROMS repository '''matlab''' and described here. The '''native''' interface was introduced in Matlab version '''2008b''' for '''NetCDF-3''' type files. The '''NetCDF-4''' support started in version '''2010b'''. The support for '''HDF5''' files was completed in version '''2011a'''. The '''OpenDAP''' support began in version '''2012a'''. If your Matlab version is older than 2008b, we highly recommend to update to the newest version. However, in the basic generic scripts we have switches for older versions to activate either the '''MEXNC''' interface for standard NetCDF files and the '''SNCTOOLS''' interface to process NetCDF files on an '''OpenDAP''' server.

Programming in Matlab is easy. However, good and efficient programming in Matlab requires skill and time. We usually become better at it the more that we practice. I started programming in Matlab in the earlier 1990's. If I look back at my earlier scripts, they were horrendous and extremely inefficient. There were some scripts that would take around 30 minutes to execute. I can rewrite those scripts nowadays and if will take seconds to execute. So we learn over the years how to program very efficiently. We are constantly learning new tricks and new functions. As ROMS, Matlab is always evolving. Plotting in Matlab take also skill. There is a lot of paper in the literature with very poor Matlab plots...

==Repositories==

To check-out the scripts described here from the ROMS repository '''matlab''', enter:

<span class="red">svn checkout <nowiki>https://www.myroms.org/svn/src/matlab</nowiki> MyDir</span>

where '''MyDir''' is the destination directory on your local computer. It will be created if not found. If your '''username''' on your local computer is not the same as your ROMS username you will need to pass the '''--username''' option to '''svn''':

<span class="red">svn checkout --username joe_roms <nowiki>https://www.myroms.org/svn/src/matlab</nowiki> MyDir</span>

Although not necessary nowadays, the '''MEXNC''' interface can be downloaded from:

<span class="red">svn checkout <nowiki> https://mexcdf.svn.sourceforge.net/svnroot/mexcdf/mexnc/trunk</nowiki> MyDir</span>

and the '''SNCTOOLS''' interface can be downloaded from:

<span class="red">svn checkout <nowiki> https://mexcdf.svn.sourceforge.net/svnroot/mexcdf/snctools/trunk></nowiki> MyDir</span>

But recall that both the '''MEXNC''' and '''SNCTOOLS''' interfaces are obsolete if you have Matlab Version '''2008b''' or newer and Matlab Version '''2012a''' for accessing NetCDF files on an '''OpenDAP''' server. See description in the [[Matlab_Scripts#Introduction|above]].

==Directory Structure==

The ROMS matlab repository has the following structure:

<span class="twilightBlue">matlab/ Main directory
/4dvar 4D-Var observations processing scripts
/bathymetry ROMS Grid bathymetry extraction and processing scripts
/bin Repository processing .bash and .sh scripts
/boundary Lateral boundary conditions processing scripts
/coastlines Coastline extraction scripts
/initial Initial conditions and climatology processing scripts
/landmask Land/Sea masking processing scripts and GUIs
/mex/ MEX interface to C and Fortran programs
/mexinside '''inside''' program
/mexrect Curvilinear and rectilinear program
/mexsepeli Sepeli conformal mapping
/seagrid SeaGrid generation GUI
/seawater Seawater properties scripts
/utility Miscellaneous all purpose scripts
/startup.m Use script configuration for Matlab
</span>

The <span class="blue">mexinside</span> program is kind obsolete since Matlab offer the <span class="blue">inpolygon</span> with the same functionality.
