Weakly Constrained Ensembles (WCE)

This package creates ensemble perturbations that have to satisfy an
+
-
a priori linear constraint.  It can also be used to create perturbations
+
-
that are aware of the land-sea mask or that use space- (or time-)
+
-
dependent correlation length.

Details of the procedure are explained in:

== Requirements ==
+
-
 
+
-
This packages requires either [http://www.octave.org GNU Octave] or [http://www.mathworks.com/products/matlab MATLAB].
+
-
If you use Octave version 3.0.5 or earlier, you need also [http://octave.sourceforge.net/arpack/index.html the Octave package arpack]. GNU Octave is a free software mostly compatible with Matlab.
+
-
 
+
-
== Installation ==
+
-
 
+
-
* Extract the package at a location that suits you
+
-
* Add the path to your MATLAB/Octave search path in the menu File > Set Path (in MATLAB) or by adding:
+
-
 
+
-
addpath('/path/to/WCE-x.y');
+
-
 
+
-
in your start-up file called startup.m in MATLAB or .octaverc in GNU Octave.
+
-
 
+
-
== Testing ==
+
-
 
+
-
The scripts wce_demo will show you several examples:
+
-
 
+
-
wce_demo
+
-
 
+
-
When using your own scripts, consider using the Matlab function "rng" to control the random numbers.
+
-
E.g., call rng('shuffle') before calling wce_simple.
+
-
 
+
-
== Examples ==
+
-
 
+
-
* [http://modb.oce.ulg.ac.be/wiki/upload/Alex/WCE_demo/wce_example_simple.html Perturbation aware of land-sea mask]
+
-
* [http://modb.oce.ulg.ac.be/wiki/upload/Alex/WCE_demo/wce_example_simple_varlen.html Perturbation with variable correlation length]
+
-
* [http://modb.oce.ulg.ac.be/wiki/upload/Alex/WCE_demo/wce_example_simple_advection.html Perturbation aligned with vector field]
+
-
* [http://modb.oce.ulg.ac.be/wiki/upload/Alex/WCE_demo/wce_example_tides.html Perturbation constrained by harmonic shallow-water equations]
