dim(1) dim(1)
NAME dim
dim - compute the dimension of convex hull and convex cone for a set of given points
SYNOPSIS
dim [-pl] filename_with_suffix_'.poi'
DESCRIPTION
dim computes the dimension of the convex hull and the con-
vex cone of a given set of points by using a gaussian
elimination algorithm. It displays the computed dimension
as a terminal message and also writes to the end of the
input file. Moreover, in the case that the input system is
not full dimensional, dim displays the equations satisfied
by the system.
OPTIONS
--pp Unbuffered redirection of terminal messages
into filename_'.prt'
--ll Use a special integer arithmetic allowing the inte-
gers to have arbitrary lengths. This arithmetic is
not as efficient as the system's integer arithmetic
with respect to time and storage requirements.
Note: Output values which exceed the 32-bit integer
storage size are written in hexadecimal format
(hex). Such hexadecimal format can not be reread as
input.
