Sensitivity analysis of odes

Hi All,

I'm solving a dynamical system uisng ode15s. The system has a lot of parameters and I'd like to perform sensitivity analysis.

I found this on file exchange https://in.mathworks.com/matlabcentral/fileexchange/1480-sensitivity-analysis-for-odes-and-daes

Is there any other toolbox available in MATLAB for performing sensitivity analysis of odes?

Thanks

I have struggled to find anything for this kind of sensitivity analysis using Matlab over the years. The function you link to doesn't allow for passing additional arguments to odefun so was rather limited when I encountered it around 5 years ago. Very little seems to have developed in the interim. For modelling with systems of ODE's, I eventually abandoned Matlab in favor of the deSolve and FME packages available for R. Julia seems to have more options than Matlab as well. I suggest exploring beyond Mathworks for this area of research.

Thank you. The link that you shared is helful. I think the first approach presented there s what most people do.
