I have a function that return a table consisting of a 2D points. These points are either {x,y} or {0,0}

function[]:=Module[{},(

  If[condition,{x,y},{0,0}](*to avoid the Null as a return I inserted the default value {0,0}*)

)]

After this I want to delete the {0,0} points from the table and leave just the {x,y}. How can I do that?

Mmmm ... After what? You only defined a function. That will do nothing (appart from creating the DownValues[] for it) – Dr. belisarius Nov 05 '13 at 03:00
It might be easier to leave the Nulls and then delete them later, as done here http://mathematica.stackexchange.com/a/34800/1783 – bill s Nov 05 '13 at 03:02
@belisarius, after using this function. – phdstudent Nov 05 '13 at 03:16
