Simulink simulation too slow

Good morning,

I am trying to run a simulink file that is devided into two sections, the first contains switches and PV systems (5 systems), and the second is the control that i get from a interpreted function. I ran each section alone and the speed is somehow acceptable, but once I run the whole simulation toghether it takes tooo much time.

What can I do to increase the speed of this simulation.

Thanks in advance.

Hey Fadi,

There are several reasons that can slow down your simulation. Here I include few possible causes:

Hope it helps!

ok the problem is from the interpreted function.

But I use this function as I have a code with many nested functions to solve a graph (digraph), how is it possible to use a matlab function instead while keeping my code as is

Interpreted Matlab Function block is slow because it calls the MATLAB parser during each integration step. Consider using built-in blocks (such as the Math Function block) instead. Here, I include a section in documentation showing how to use it with some example:
