%% Improve Appearance of Surface Plot % Plot the expression |f|. Improve the appearance of % the surface plot by using the properties of the handle returned by % |fsurf|, the lighting properties, and the |colormap|. % % Create a light by using |camlight|. Increase brightness by using |brighten|. % Remove the lines by setting |EdgeColor| to |'none'|. % Increase the ambient light using % |AmbientStrength|. For details, see <docid:matlab_visualize.f1-21767>. Turn % the axes box on. For the title, convert |f| to LaTeX using |latex|. Finally, to % improve the appearance of the axes ticks, axes labels, and title, set % |'Interpreter'| to |'latex'|. syms x y f = 3*(1-x)^2*exp(-(x^2)-(y+1)^2)... - 10*(x/5 - x^3 - y^5)*exp(-x^2-y^2)... - 1/3*exp(-(x+1)^2 - y^2); h = fsurf(f,[-3 3]); camlight(110,70) brighten(0.6) h.EdgeColor = 'none'; h.AmbientStrength = 0.4; a = gca; a.TickLabelInterpreter = 'latex'; a.Box = 'on'; a.BoxStyle = 'full'; xlabel('$x$','Interpreter','latex') ylabel('$y$','Interpreter','latex') zlabel('$z$','Interpreter','latex') title_latex = ['$' latex(f) '$']; title(title_latex,'Interpreter','latex')
