Follow-up Comment #14, bug #31287 (project octave):

Octave already conforms to "rule 2.2", i.e. the dimensions of the indexed
expression on the LHS and the dimensions of the RHS do match for successful
empty assignment, with the "exception" that dimenensions being 1 can
additionally be present at non-matching positions and numbers.

But for matrices ("rule 2.1"), Matlab allows any assignment as long as
indexed LHS and RHS are both empty, but Octave does not.
