I get the results:
 
octave-3.2.4.exe:242> __gnuplot_version__

ans = 4.4.0

 

 

octave-3.2.4.exe:243> clf;plot (0:10);print -demf "-S640,480" test.emf;

warning: implicit conversion from matrix to string

octave-3.2.4.exe:244> octave-3.2.4.exe:244>

 
 
thank you very much for your instructions, i am learning how to use the mailist.
