' Plot a "simple surface" directed field.

F{x,y} = y^(1/3)
G{x,y} =x^(1/3)
H{x,y} =Exp[-F{x,y}]+ Exp[-G{x,y}]

PlotDirField[F, G, H, {-3,3,25}{-3,3,25}]

' After the graph is displayed:
'     Use the cursor keys to get a better angle of view;
'     Color the axes to see it relative to the image.

'     Click on the box option; color the axes to see it.
