Fcn convert to Matlab Function in Simulink

I use R2022a version of MATLAB, Simulink. However, I have to use fcn but this version doesn't have this function. I have to Matlab Function. Such as I write sqrt(3)*u(1)*u(3)/u(2) for fcn. How to write this function with Matlab Function using Simulink? Can you help me for this problem?

Hi @Sule Soylu,

I understand that you are trying to write function using MATLAB function using Simulink. Referring the following information might be of good help to you.

1. First add MATLAB function block in Simulink.
2. Then Click on MATLAB function block.
3. Then you will see a function like this.

function y = fcn(u)

y = u;

4. Now, replace y = u ; with your equation. See below

function y = fcn(u)

y = sqrt(3)*u(1)*u(3)/u(2);

Here u is input to MATLAB function block and y is output.

For more information about MATLAB function block, refer to the following page
