SIGMA - A SWAN Graphical Interface in MATLAB®
SIGMA is a MATLAB® user interface. The program has several purposes: Provide a graphical interface for preparing SWAN simulations (loading bathymetry, organizing input files etc). Help organize and generate a humanly readable INPUT file. Provide an interface for visualizing the output of simulations.
Sigma 1.001: Contains minimal patches for Sigma 1.0:
- Corrected placement of dialog windows. On a small screen all dialog windows should be visible now.
- The code has been re-tested with MATLAB® Linux version 220.127.116.11 (R14) Service Pack 3. On this version the function contourf is broken. The directional spectra are now drawn using surf.
Sigma 1.0: The code was developed and tested on the MATLAB® Linux version 18.104.22.1682 (R14) Service Pack 2, released January 29, 2005.

Not all the interface functions are documented. Not all the interface functions are operational. The interface does not implement all the input functions available in SWAN.
The code provided here is the result of intermittent work by Alex Sheremet, over a number of years, written and re-written many times over, mainly driven by his own nebulous ideas and needs at the time and in blatant disregard of common sense, logic and other people's patience limits.
There is no implied guarantees that it may serve any purpose whatsoever. The user is strongly cautioned not to rely on it for any activity which may have significant consequences. Alex Sheremet will not be held liable for any consequences resulting from the use of this code.
