How to use "Callback" while solving differential equation with uncertain initial condition and uncertain parameters?

Hello all,

I am solving nonlinear differential equation using “ReachabilityAnalysis.jl” package (Example: Lotka-Volterra · ReachabilityAnalysis.jl). Both initial condition and parameters are uncertain, so I tool intervals of parameters. I wish to check the sensitivity of the system against the perturbation in parameters. To check that I perturb the parameters’ intervals in between the simulation time. Please let me know how to do that using “Callback” function (Example of callback: Event Handling and Callback Functions · DifferentialEquations.jl).

Thank you
