Octave's contour function

[Fernando Fraga e Silva]

I couldn't figure how to use the function "contour" by reading the info 
manual about this one. I missed a simple example as a pattern to learn to use 
it. Does anyone here could send me a little example about it ?

I need to plot the contour of a function f(x,y).

I'm really thanks .
