If this is what you mean, http://mathworld.wolfram.com/FoliumofDescartes.html,How can I draw the Folium of Descartes in Octave? In Matlab I did:f = sym('x^3x^2+y^2'); ezplot(f)Various Octave tutorials explain how to draw simple functions in one variable, but I can't find a way to draw functions in two (or more) variables. I'm a very newbie of Octave (and Matlab too), maybe it's silly questions  in this case, sorry :) Thanks in advance, G.L.
then, you could do it using, %parameter t = linspace(5,+5,100); a = 1; x = 3*a.*t ./ (t.^3 + 1); y = 3*a.*t.*t ./ (t.^3 + 1); plot(x,y,'o;folium of descartes;') gives a reasonable picture. Tune 't' for more detailed plot. Muthu
