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.
