Today I started learning Simulink, and think I can wrap my head around it. However, I came to the definition of the definition of the "Memory Block":
Definition: The Memory block holds and delays its input by one major integration time step.
I don't really understand what that means. I understand that converting from a continuous to discrete time is a very useful thing (and from what I understand, a "zero order hold" is the way to do this), but the use of a memory block as defined above is rather confusing to me.
Can someone explain in layman's terms what it does?
