gnuplot had always "gnuplot binary" format for (skew) matrices -- but Octave 
didn't used the.

On a similar topic, command
 	tmp> plot(hilb(10))

produces 10 temporary files and asks gnuplot to draw them. Why there is not 
a single file? That would be plotted much faster.

My previous letter shows that Octave still does not use gnuplot 4.0 features 
(released almost 2 years ago) enough.
