Need a code example of sensitivity analysis

hello, i have estimated a dsge model via a bayesian approach. Nox i want to perform a sensitivity analysis to analyse the behaviour of certain variables according to the the variations of interest parameters. Now i really need an code example to lean on it for my work

Thanks in advance.
