In Octave 2.1.50 on Linux, it doesn't look like your octave_randn figure 
above, it looks like the matlab_randn except that the points are all red 
instead of blue and green.  The distribution in your octave plot is all 
wrong - the points are not normally distributed.  Is it possible that you 
somehow defined a new randn function?  Your distribution in Octave is a 
strange, symmetrical mixture.
