Hi everybody! I'm always in troubles when trying to use polymake. It is very nice to find this space here to ask. This must be an easy question, since I don't quite grasp how to read the documentation. I'm trying to use the command
projection to eliminate the last coordinate from a 7-polytope. How should I specify the array of indices? For example, I tried the following...
Code: Select all
$R=projection($P,{0,1,2,3,4,5,6});
polymake: ERROR: projection: polyhedron full-dimensional, don't know where to project on
In this case $P is a full dimensional 7-polytope, but I am only interested in its projection. The first 0 index was supposed to mean the first 1 coordinate on the vertex description. What is the right way to do it?
I have similar problems with most of the things I try to use. Maybe it would be nice to have small examples of code that work for the different items on the documentation. Thanks for anything that could help... See you!
