It appears that the MATLAB and Octave versions of "double" do different 
things, partly because MATLAB allows for non-double data types which 
aren't (yet) supported in Octave. This function should run fine if you 
just removed the call do double and did

n = floor(real(n(1)));

That said, you can solve all of your problems by using the version of 
magic.m that is included in Octave-Forge (http://octave.sf.net).
