Hi
I am trying to run a model (not written by me). When I open it in 2019a matlab version I have a number of variables that are seen as global by matlab (change color). But when opening them in 2020a version these variables are not global. This is the same code in both cases. Did something changed in the global variable definition in 2020a?
Thanks for your answer

My suspicion is that you're not actually using global variables, you're using variables shared between a function and another function nested inside the first. There were some changes in release R2019b in this space; see the Release Notes for more information. My guess is that you were implicitly sharing those variables between the parent and nested functions.

Thank you. I think your suspicion was right. I tried looking for a global variables definition in the code but couldn't find any. Thank you for your help.
