[Haskell-cafe] Finding points contained within a convex hull.

Hello.

I've got a system of linear inequalities representing half-spaces.  The 
half-spaces may or may not form a convex hull.

I need to find the integral coordinates that are contained within the convex 
hull, if there is one.

For example, given
0 <= x <= 4
0 <= y <= 3
0 <= 2x - y
0 <= 1.2y - x

I want the following (x,y) coordinates
[(0,0),(1,1),(1,2),(2,2),(2,3),(3,3)]


Anybody have any suggestions, or libraries, for solving this in many 
dimensions and equations?


Thanks
Daniel
