Details:

In Matlab I get the following output from repmat:

>> repmat([1,2,3], [], 4)

ans =

     1.0000e+000     2.0000e+000     3.0000e+000
     1.0000e+000     2.0000e+000     3.0000e+000
     1.0000e+000     2.0000e+000     3.0000e+000
     1.0000e+000     2.0000e+000     3.0000e+000

>> repmat([1,2,3], 2, [])

ans =

     1.0000e+000     2.0000e+000     3.0000e+000
     1.0000e+000     2.0000e+000     3.0000e+000

>> repmat([1,2,3], [], [])

ans =

     1.0000e+000     2.0000e+000     3.0000e+000

Empty arguments appear to be treated as 1. Octave does not permit this
behaviour.
