I ran some comparative speed tests. A good example was ...

        tic; for n = 1:1e6; a = str2double ('1+1i'); end; tic

In this test, Octave is about 7x faster than Matlab.

Perhaps Octave's unexpected behavior is feature of its improved performance?

p.s. I took a quick look at str2double.cc but since c/c++ is a big weakness for 
me I can't tell if this unexpected behavior can be fixed without slowing things 
down.
