A discussion about installation problems concerning the polymake workshop version 2.9.10 on openSUSE 11.4 can be found here: script "tarballs" not working

Could you specify the problem with the installation of polymake 2.9.10? Is there an error message? Maybe, the correct version of GMP or MPFR is missing...

Thanks for asking this essential question! You can define a polytope in polymake by specifing a matrix of POINTS or INEQUALITIES as follows: $inequalities=new Matrix<Rational>([[1,1,0],[1,0,1],[1,-1,0],[1,0,-1],[17,1,1]]); $p=new Polytope<Rational>(INEQUALITIES=>$inequalities); Then you can ask for ...

Sure, questions like that are very welcome!

The documentation says Parameters Polytope P Array<Int> indices So if the syntax you try does not work, it is always possible to specify the indices in an extra variable: $coords=new Array<Int>(1,2,3,4,5,6); $R=projection($P,$coords); That way you can directly use the data type you find in the docum...

lp2poly() returns a Polytope<Float> , which does not provide all the properties you need for your task. Therefore, you should convert it to a Polytope<Rational> via the user function convert_to<Rational>() , i.e., $p=lp2poly("/my/file.lp"); $p_rat=convert_to<Rational>($p); Now one way to ...
