Details:

When calling cross() with a column vector and a row vector or a row vector and
a column vector Octave will return a column vector (and a warning) while
Matlab will return a row vector.

In octave for example:

> cross([1,2,3]',[0,0,1])
warning: cross: taking cross product of column by row
warning: called from
    cross at line 62 column 7

ans =

   2
  -1
   0

 In Matlab:

>> cross([1 2 3]',[0 0 1])

ans =

     2    -1     0


In general, Matlab will only return a column vector if both vectors are column
vectors and Octave will only return a row vector if both vectors are row
vectors. This can break script compatibility.
