Hi Hermes,
One simple way is to display the 0-contour level of your "heart" function: // START OF CODE nx = 300; ny = 200; X0 = linspace(-1.2,1.2,nx); Y0 = linspace(-1.5,2,ny); X= X0.*.ones(ny,1); Y= (Y0.*.ones(nx,1))'; Z = (1.2*Y - sqrt(abs(X))).^2 + X.^2 - 1; // Heart function clf() a=gca(); a.x_label.text=" X"; a.y_label.text=" Y"; contour(X0,Y0,Z',[0 0]); a.view = "2d"; // END OF CODE Exercise: fill it in red...

Please, could you help me? <http://mailinglists.scilab.org/file/t497622/Heartcurve.jpg> Gracias -- Sent from: http://mailinglists.scilab.org/Scilab-users-Mailing-Lists-Archives-f2602246.html _______________________________________________ users mailing list [email protected]<mailto:[email protected]> http://lists.scilab.org/mailman/listinfo/users
