Re: string-arrays - different behavior of{} in Win2000 and debian linux

[TAltman]

This observed behavior is due to Octave's cell literals requiring a comma 
between elements. If memory serves, adding commas in won't break your Matlab 
script(s), because in analogy to array literals, the comma delimiter is 
optional ( please correct me if I'm wrong ).

Thanks,

~Tomer Altman
