How do I analyse the needed amount of dynamic memory for a Simulink Model?

I'm working on a project for which I want to analyse the amount of dynamic memory a Simulink Model would need on a processor (Matlab R2021b).

I already found some nice analysis functions for static memory and run time inside the embedded coder toolbox, but sadly there are no information about dynamic memory analysis.

After I spent quite some time searching through the internet for a solution, I still couldn't find any function for this.

Does anyone know a way how dynamic memory usage can be analysed?

Thanks in advance!

Hi Philipp, I've exactly the same need as you. Did you manage to find a work around?

Try the following ways to analyse the dynamic memory requirements-

1. Run the Simulink model and type the command “memory” in MATLAB command window.
2. Use Task manager in window. Run the simulation and check the amount of memory used by it in the Task Manager.

As far as I understand "memory" it shows the capacity of RAM for your PC and the amount Matlab is currently using (not only for the current skript, but also to run the development environment). But I'm interessted for the RAM that is used only for the execution of a certain Simulink Model, that is later used on an embedded system. The numbers I get from "memory" are a lot higher than expeceted for this (screenshot). Is there a way to show how much RAM Matlab uses for certain purposes?
