Hello! As we know, the s-function builder block enable to run simulation based on user specified C source code.For example, I can link "mycode.c" to s-function builder tool then execute functions reside in "mycode.c" when doing simulation.Picture below shows you the setting I have made.
But now I have a problem. I found that the static variable declared in "mycode.c" seems not stay static in Simulink .
Since the static variable in "mycode.c" is important for my simulation. How to make the variable static in MATLAB environment? Thank you in advance!

Hi yivan,
I am currently interested in a solution for this necessity.
A workaround that I made for my case, was to declare a function the would set or get the value of the static variable.
If you or someone else found an elegant solution for this problem, I would be glad to listen to.
