poly.x(1)
computes data of a polytope
Description
POLY.X
NAME
poly.x, poly-<num>d.x - computes data of a polytope
SYNOPSIS
poly.x [-<Option-string>] [in-file [out-file]]
DESCRIPTION
Computes data of a polytope P
The poly-<num>d.x variant programs, where <num> is one of 4, 5, 6 and 11 work in different dimensions ; poly.x defaults to dimension 6.
Options (concatenate any number of them into <Option-string>):
