can I return more than one argument in the "odefun" when called from ode45

I am attempting to integrate a differential equation for a system manifesting state changes, such that the prior state must be passed to "odefun" in each call executed by ode45. Is it possible to allow odefun to return more than one variable (after the estimated numerical derivative) to facilitate this? Or is there another alternative?
Thanks.

What you've described sounds not like an ordinary differential equation (ODE) but like a delay differential equation (DDE). This documentation page describes the functions available for solving DDEs.
