[student] Asking your help to solve an issue with a function creating algebric loop

Hi,

I am a french student (it might be senior year for you), and iam working on a project for my Ingeniors science class.

I need your help to know if I can change a function that I need ( or not I don't know ) in my simulation. ( The fact is that i wanted to speed up the simulation but the algebric loop forbids me from doing it

Here is the function

function MW = fcn(consigne)
if consigne >= 0
    k = 128/100;
else
    k = 127/100;
end
MW= round(k*consigne) +127;
end

if you need any precision feel free to ask me

Have a nice day

The problem is not that block: the problem is that you have blocks in which the output is connected to the input, but the calculations are not marked as taking time.

Thanks for your answer, I don't quite get it for the moment but i will take a look on it.

moreover do you have any idea for me to find the location of the algebraic loop ?
