			==The Matlab ROMS_WILKIN tool-kit==
			John Wilkin (jwilkin@rutgers.edu) provides a set of matlab m-files that read ROMS netcdf files using SNCTOOLS, and create simple plots, extract data subsets (e.g. slices at constant depths), or perform simple operations on data (e.g. depth integrals). Most of the tools optionally return the data that form the basis of each plot and the graphics handles so that you can replot according to your own requirements if desired. The tools are designed primarily to work with 'realistic' model output in longitude and latitude coordinates, but will replace the lon/lat with ROMS x/y coordinates if necessary.
			# How to use the tools and instructions for download are provided via tiddlywiki at [http://romsmatlab.tiddlyspot.com/ romsmatlab.tiddlyspot.com]
			# There is some discussion of these tools at [https://www.myroms.org/forum/viewtopic.php?f=23&t=916&start=0&hilit=roms_wilkin this thread] on the User Forum.

	MATLAB is powerful software that is commonly used to create ROMS inputs and to visualize and analyze ROMS output. However, out-of-the-box Matlab doesn't come with the capabilities to read/write ROMS NetCDF files. For that you need to download and install MEXNC, which is a mex-file interface to NetCDF files for MATLAB. In simple terms, it is a set of files (mex and .m files) that allows Matlab to read and write NetCDF files. Also, if you want to fully exploit Matlab's capabilities to manipulate/analyze ROMS files, you may want to download/install SNCTOOLS and the ROMS Matlab tool-kit, which are Matlab routines (that sit on top of MEXNC) that facilitate the manipulation, visualization and analysis of ROMS input/output NetCDF files. There are free alternatives to Matlab (see links below), however in this tutorial I will only review (some) tools for Matlab.
