how to convert matlab code to simulink?

Hello people,

I'm a new user of Simulink.
i wrote an algo' for pupil detection in matlab, now i want to convert this code to simulink code because i want use my algo on real time camera.
in my algo i'm using "BWlabel","Edge Detection" of matlab, i know that in simulink there is special blocks of "BWlabel" and "Edge Detection",
but if i'll use it i'll need to break down my matlab code into a large number of embedded matlab blocks, i'm looking for a way to avoid
this action.

thank you for your suggestion,
Aviv.
