%% Modify Contour Plot After Creation % Plot the contours of $e^{-(x/3)^2-(y/3)^2} + e^{-(x+2)^2-(y+2)^2}$. % Assign the function contour object to a variable. f = @(x,y) exp(-(x/3).^2-(y/3).^2) + exp(-(x+2).^2-(y+2).^2); fc = fcontour(f) %% % Change the line width to |1| and the line style to a dashed line by using % dot notation to set properties of the function contour object. Show % contours close to |0| and |1| by setting the |LevelList| property. Add a % colorbar. fc.LineWidth = 1; fc.LineStyle = '--'; fc.LevelList = [1 0.9 0.8 0.2 0.1]; colorbar
