Follow-up Comment #13, bug #50202 (project octave):
I believe the following Matlab documentation page describes how it handles
indexed assignment, including what it does if the object doesn't exist:
https://www.mathworks.com/help/matlab/matlab_oop/indexed-assignment.html
specifically:
"If A does not exist before you execute the assignment statement, then MATLAB
initializes the five array elements that come before A(2,3) with default
objects of class B. "
So as said in comment #9, this default object is 0.0 for floating point
numbers, 0 or false for logical, etc. but it may not be 'null' for other
classes. I've never messed with classes, but I assume a 'default object' is
defined when one is created. Is there any case to verify that Octave follows
that behavior if the default is not a 'null'?
