Unit Delay Block using Matlab Function Block in Simulink

I would like to replace the unit delay block in simulink with a matlab function block. However, I don't know what to write for the code inside the matlab fcn block to be able to get the exact same results as the unit delay block. Any help on this?

I do not think that is possible using a MATLAB Function Block. I think you would have to use a Level-2 S Block (potentially implemented in MATLAB.)

thank you Mr.Roberson for your quick reply. I will try to figure another way.
