global sensitivity analysis test

I have corelation obatined for average Nusselt number as a function Reynolds number, normalized amplitude and pitch of corrugation. I wanted The Reynolds number rangs from 5000 to 30000, normalzied amplitude from 0.02 to 0.05 and normalzied pitch from 0.08 to 1.1. can someone help me out on how to perform global sensitivity analsyis

there are available tools for you , like :

Global Sensitivity Analysis Toolbox - File Exchange - MATLAB Central

A Matlab toolbox for Global Sensitivity Analysis - University of Bristol

Hi,

To perform global sensitivity analysis, download a MATLAB toolbox GSAT (Global Sensitivity Analysis Toolbox https://www.mathworks.com/matlabcentral/fileexchange/40759-global-sensitivity-analysis-toolbox). It support methods like Sobol, FAST, and Morris, and let you define your function in a GUI or live script. Then simply run the analysis and instantly get sensitivity indices and visualization plots that show which parameters and interactions most affect your Nusselt number.

I hope it helps!

Thank you very much for your response. I have been able to add the path of GSAT to my MATLAB. However, I have not been able to run my analysis. You mentioned here that there is GUI for GSAT please I need more information on how to use it in MATLAB. Thank you
