thank you all the same, i solved the problem;
now i'd like to know the following if you can give me some advice:
when i use these lines:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
gset title  "angle - radius; N = 50"
gset xlabel "radius [m]"
gset ylabel "angle [rad]"
gset term postscript eps color
gset output "angle_to_radius.eps"
replot;
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

i get this warnings:
warning: gset deprecated and will be removed from a future
warning: version of Octave.
warning: You should use the higher-level plot functions
warning: ("plot", "mesh", "semilogx", etc.) instead
warning: of the low-level plotting commands.
warning: If you absolutely must use this function, use the
warning: internal version __gnuplot_set__ instead.

i checked in the online manual but did not find anything really
useful; i'd like to know how to handle the interaction between octave
and gnuplot, such as to take control over all the capabilities of
gnuplot from inside an octave code: can you please address me to some
online reference where i can get this information?

thank you all
