MATLAB: Warning while overwriting a workspace variable

Question

Hello all,

is there a way a notification (warning/error/log) be issue when a base workspace variable is overwritten?

Details:

I have number of constants and parameters defined in various .m scripts.

I fear there might be constants with different values in some of the files . So whenever a variable is overwritten, I want to have some alert/logging.

Is this possible?

Basically, if a variable to be added to the workspace already "exists", it (some hook function or so) should somehow notify.

Thanks

While you can do this for certain types of variables (create a class and have that class's delete method issue a warning when executed) I'd propose a different solution. Since you mention this is in the context of a Simulink® model, consider using one of the other data storage techniques described on this documentation page. I haven't used these techniques myself, but based on your use case it sounds like a data dictionary may be useful in sharing data between the various models the different people or groups of people have written.
