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.

Page 2, yes apparently you do get IML with that package.

Do you know if you can use the CVEXHULL Function in the university edition? there in an * next it so I'm not sure if this is included.

Afraid I have not used UE. Perhaps consider posting request for information in the SAS UE domain, or the IML domain as this isn't really graph related.
