Follow-up Comment #1, bug #51784 (project octave):
The mex api call that I am referring to looks like this:
mexGetVariable("global", "SOME_GLOBAL_VARIABLE");
If SOME_GLOBAL_VARIABLE doesn't exist GNU Octave currently returns a null
matrix (zeros(0,0)), and according to Matlab documentation and Matlab behavior
mexGetVariable should return nullptr in such a case.
