Can I add arguments to the odefun in ode45 integration?

I am running a loop. During each iteration, I perform integration from a fixed initial state. To fulfill my objective, I need to change my state function(odefun) before the next iteration begins. In order to do that, I would need the following arguments to get my new state function for the next iteration: 1. a vector which is an output from the previous integration. 2. a number which comes from the previous integration.

How do I go about it?
