I am trying to model drug delivery over time using ODE45 to simultaneously solve three differential equations, and it is giving me an exponential decay function, which is what I want. However, I am now trying to model extra doses being applied to the system. For example, I want to increase the concentration of the drug by a set amount at a certain time interval while having the exponential decay still apply. Basically, I want it to look like this:
