Opustc Overview

Description

This toolbox allows to compute the output Y of a numerical simulation, given its uncertain input X and its deterministic input D. Each numerical model is in the form:

      
Y = opustc_case ( X , D )
   
    

where

This toolbox has been created in the context of the OPUS project :

http://opus-project.fr/

within the workpackage WP3 : "Validation et démonstration".

This project has received funding by Agence Nationale de la recherche :

Quick start

In the following example, we define the input X as a 1-by-15 matrix of doubles, and compute the output Y of the couplex benchmark. Here, Y is a 1-by-168 matrix of doubles. The deterministic parameters D have here been set to their default values. This function call requires approximately 15 seconds.

X = [25.0 3.0e-6 6.0 3.0e-5 1e-6 5.0e-4 50. 50. 50. 50. 21. 51. 3. 110. 160. ];
Y = opustc_couplex ( X )

In the following session, we enable the verbose mode.

D = init_param();
D = add_param(D,"verbose",%t);
Y = opustc_couplex ( X , D );
