I don't have SAS/IML license so I was wondering if there is an algorithm that can be used in SAS/STAT or Base? I don't mind if it's not that efficient or is a bit messy. I want to calculate the convex hull of lots of 8 point polygons simulated as follows:
do i= 1 to 8;
x= round(1000* ranuni(123),1);
y= round(1000* ranuni(789),1);

Here is a link some algorithms, and there is liknk to Qhull there which may also help.

I'm interested in getting the convex hull of a two dimensional polygon - the volume of a polytope is not what I'm looking for.
If you download the student university edition of SAS do you get SAS/IML? I know you can do it fairly easily there.
