[Octave-bug-tracker] [bug #47298] zeros() with empty dimensions but non zero rows or columns does not fail

[Markus Mützel]

Follow-up Comment #2, bug #47298 (project octave):

For what it's worth:
Matlab R2012a does not fail on

zeros(zeros(1,0))


but it produces an empty matrix of size 0x0.
This seems to be the only case where you can pass empty matrices to zeros(),
ones(), Inf() or NaN() without provoking an error.

I am not sure whether this is an error in Matlab or whether its behaviour is
correct. After all, the documentation [1] states that the input argument sz is
the "Size of each dimension, specified as a row vector of integer values." You
could argue that a 1x0 vector was a row vector. Thus, a matrix with "no
dimensions" should be returned...

The function nan() behaves the same as described in #comment 0 and is not
touched with your patch. Maybe you could fix it, too?
