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.
- First add MATLAB function block in Simulink.
- Then Click on MATLAB function block.
- 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
