You have not written an S-function, but just a MATLAB function in a format that Simulink will not understand. Please go through the documentation for MATLAB S-functions and look at some of the demos to understand how to right S-functions.

with my code, how do I could turn into a block in the "simulink"

duc1 duc2: Sorry, I'm really having trouble figuring how to answer better to help you understand. I've pointed you to the right documentation, but it's not clear whether you've been reading any of it because you've been asking the exact same question over and over again.
