[Octave-bug-tracker] [bug #55622] for loop does not run over a matrix with colums but no row

[Muhammad Yasirroni]

Follow-up Comment #18, bug #55622 (project octave):

I don't understand why we debate over an empty matrix. Clearly, the column
vector is not empty at all. So, we should iterate over it.
Furthermore, if we got it as a result of a function, we sometimes didn't check
the dimension of our matrix, such as:


b=[3;1;2];
[sorted_b, indices] = sort(b);
size(indices)
for a=indices
    disp('loop')
    disp(b(a))
end

ans =

   3   1

loop
   1
   2
   3


When we expect that we are able to iterate over indices.
