how do i run a mex code in a matlab function block

I have gotten a mex code but I don't know how to run this code on a MATLAB function block. The function block is part of a smulink model.

If you have a compiled mex such as a .mex64 file, then those files are treated like built-in commands whose name is the name of the mex file. You can refer to them by name in your MATLAB Function Block, without needing anything special, just as if they were a Mathworks-provided routine.

Thanks but please how can I refer to it?

By name. For example in your MATLAB function block

function result = func(u)
  xyz = zeros(1,20);
  xyz = NameOfMexFile(u);
  result = sqrt(xyz);
