This tutorial allows you to complete a sensitivity analysis of the following analytical nonlinear function:
The function has additive linear and nonlinear terms and one coupling term.
Contribution to the output variance (reference values):
X1: 18.0%
X2: 30.6%
X3: 64.3%
X4: 0.7%
X5: 0.2%
This tutorial demonstrates how to do the following:
Generate a solver chain using MATLAB
Define the parameters and responses
Specify parameter properties
Before you start the tutorial, download the coupled_function_matlab zip file from here , and extract it to your working directory.
To set up and run the tutorial, perform the following steps:
In the Select input file dialog box, browse to the coupled_function_matlab folder and select coupled_function.m.
Click
.
From the Detect assignments drop-down list, select .
In the MATLAB table, select rows 13-17 (X1 to X5) and drag them to the Parameter pane.
In the MATLAB table, select row 18 (Y) and drag it to the Responses pane.
Click
.
To highlight all of the parameters in the table, do one of the following:
Click the name of the first parameter, press Shift, and then click the name of the parameter the last row.
Click the name of the first parameter, then with the mouse key pressed, pull down to the last parameter and release the mouse key.
While pressing the Shift key, double-click the range numbers in row 5.
Change the lower bound to
-3.14
and the upper bound to3.14
.Press Enter.
The range of all of the parameters changes to -3.14 and 3.14.
Click
.
Do not adjust or add to the currently displayed values for parameters, responses, and criteria.
Click
.
Select the Create a template from solver chain check box.
Click
.The template is displayed in the Scenery pane.
