Code generation ignores my matlab function in simulink

I have a matlab function which has one input and no output. I get some data from inport into this function and dump those variables into global variables that already exists in the workspace. However, Simulink code generation completely skips this matlab function and I'm not sure how to force it to go through those assignments.

Goal: I'm trying to update some variables that are used throughout the model using inports.

Hi Aaron, it is hard to figure out the problem without seeing an example. Do you have a simple model that you can attach, along with the reproduction steps?
