How to apply NonNegativity constraint in ODE solver when defining ode as a structure

I am trying to perform a local sensitivity analysis on the parameters of my model using odeSensitivity. Taking help from this page https://in.mathworks.com/help/matlab/ref/odesensitivity.html. but the problem is that when I used to code the ode simply I put nonnegativity under options, but now i am not able to do that. I tried taking F.NonNegative=ones(1,n_parameters) but that doesnt seem to work.

The relevant property of the ode object to specify that some of the variables must be non-negative is NonNegativeVariables. After you've set up that property, create the odeSensitivity object and set it to the ode object's Sensitivity property.
