Global variables and multiple licenses of Matlab

Hello everyone,
At the moment I'm running multiple Matlab licenses on the same computer. My analyses utilize the same function m-file which uses global variables.
Can anyone tell me if these different instances of Matlab are able to access and use the single function file, without interfering with one anothers calculations?
Thanks in advance!

Each instance of MATLAB is completely independent. Things like global variables are local to the instance of MATLAB that created the variables. If you are accessing hardware like a disk or serial port you can run into problems. Potentially doing things on a GPU could be problematic. In general you shouldn't have any problems.

In fact, the other way around is complicated: Sharing variables between Matlab sessions requires very smart strategies, see FEX: sharedMatrix.
But beside the warning, that global variables are a bad programming style, you can run into troubles, when you store them temporarily on the disk due to collisions.

Good to know, thank you both!
