How to tell if a function was called from within Matlab or from system?

I've been running Matlab code on a high performance cluster, but while debugging it is useful to run it in an interactive matlab instance for plotting and such. However, I would want my code to do different things when called from the cluster compared to when it's called interactively in the matlab GUI. My specific case is using bash to call my matlab function in a unix-based cluster.
Is there a way to programmatically determine from which environment a Matlab function was called from?

Perhaps you might try what are essentially different calls, where you pass information about WHERE your call is coming from. So subtly different calls to the same function, but one of the arguments to that function is now an indicator variable that will change the behavior of the function.

isunix() will be true on the cluster, or on desktop Linux or Mac systems, but not on Windows systems.
If your desktop is Mac, then ismac() is true. Contrawise, isunix() && ~ismac() implies linux()
When isunix() is true,
HN = system('hostname')
would permit you to differentiate between different Linux hosts you run the code on.

Set an environment variable in the bash script and in the matlab code check the environment variable with getenv()?
