The GSUA Toolbox implements uncertainty and sensitivity analysis (global and OAT) of dynamical (with differential equations) and static (functions) models. The Saltelli and brute-force global sensitivity methods [2] are implemented. The one-at-a-time (OAT) local method is applicable correctly only if the interaction between factors is small, so first-order sensitivity indices should be carefully reviewed. The toolbox needs the following two files: 1) The gsua_main.mlx file. 2) A mathematical model in a slx-file (Simulink) or m-file (ode45), as shown in the examples given in the toolbox. See help at the end of gsua_main.mlx file for more information. Several examples are included.
