1. 
   
2. [X,Y] = meshgrid(-2:.2:2,-2:.2:3);
   
3. Z = X.*exp(-X.^2-Y.^2);
   
4. [C,h] = contour(X,Y,Z);
   
5. set(h,'ShowText','on','TextStep',get(h,'LevelStep')*2)
   
6. colormap cool
   
7. hold on;
   
8. Z = X.*exp(-2*X.^2-0.5*Y.^2);
   
9. [C,h] = contour(X,Y,Z);
   
10. set(h,'ShowText','on','TextStep',get(h,'LevelStep')*2)
    
11. colormap cool
