Simulink S-function PID controller implementation

Hello all,

I have a discrete PID controller implementation in C language and I would like

to analyze its behavior in various modes of operation. I have decided to use

the Simulink S-function for that purpose. Can anybody direct me to some tutorial

describing how to implement such discrete dynamic system in S-function?
