[Octave-bug-tracker] [bug #38423] [k:l:m] not compatible for m = -0

[Dan Sebald]

Follow-up Comment #9, bug #38423 (project octave):

[Note type in "help typeinfo": "return an cell array".]

OK, I understand now.  min and max have to return a type double matrix and
Octave is retaining the underlying dimensions of the operations even though
they are empty.  Further examples:

octave:24> (1:1:3)'*[1 1]
ans =

   1   1
   2   2
   3   3

octave:25> (1:-1:3)'*[1 1]
ans = [](0x2)
octave:26> (1:-1:3)*[1 1]
error: operator *: nonconformant arguments (op1 is 1x0, op2 is 1x2)

octave:28> ones(0,0)
ans = [](0x0)
octave:29> []
ans = [](0x0)
octave:30> typeinfo(ones(0,0))
ans = matrix
octave:31> typeinfo([])
ans = null_matrix
octave:32>
