%% Modify Contour Plot After Creation % Plot the contours of $e^{-(x/3)^2-(y/3)^2} + e^{-(x+2)^2-(y+2)^2}$. Specify an output to make % |fcontour| return the plot object. syms x y f = exp(-(x/3)^2-(y/3)^2) + exp(-(x+2)^2-(y+2)^2); fc = fcontour(f) %% % Change the |LineWidth| to |1| and the |LineStyle| to a dashed line % by using dot notation to set properties of the object |fc|. Visualize contours % close to |0| and |1| by setting |LevelList| to |[1 0.9 0.8 0.2 0.1]|. fc.LineStyle = '--'; fc.LineWidth = 1; fc.LevelList = [1 0.9 0.8 0.2 0.1]; colorbar
