[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
