[Octave-bug-tracker] [bug #34868] subsref crashes octave

[Rik]

Follow-up Comment #11, bug #34868 (project octave):

Isn't the analogy closer to indexing with an empty matrix than horzcat with
empty arguments?

It seems like subsref with a null index is conceptually equivalent to


x = 1:10;
idx = [];
x(idx)
ans = [](0x0)


It appears most reasonable to either flag an error, as Matlab does, or return
an empty matrix since that is what the corresponding index code would do.
