I am learning Simulink. I've done around 50% of the onramp course so I tried modeling something on my own.
One of the reasons I wanted to learn simulink is to model population models so that's what I started with. The problem is, however that it's a recursive model and I don't know how to make this work in simulink...
The below is what I tried:

If the population model can be represented as a discrete state-space system, then the appropriate approach would be to utilize the Discrete State-Space block.

If you found the suggestion regarding the Discrete State-Space block and the rounding issue helpful, please consider clicking 'Accept' ✔️ on the answer. Do you primarily deal with discrete systems?

By the way, is your population model continuous or discrete? For instance, if the current population count is 34, it wouldn't make sense to have 3.4 births (where 0.4 represents half-alive individuals) or 6.8 deaths (where 0.8 indicates individuals on the brink of death), correct?
