  <longdescription lang="en">
    The C-library  cddlib is a C implementation of the Double Description
    Method of Motzkin et al. for generating all vertices (i.e. extreme points)
    and extreme rays of a general convex polyhedron in R^d given by a system
    of linear inequalities:

    P = { x=(x1, ..., xd)^T :  b - A  x  &gt;= 0 }

    where  A  is a given m x d real matrix, b is a given m-vector
    and 0 is the m-vector of all zeros.

    The program can be used for the reverse operation (i.e. convex hull
    computation).  This means that  one can move back and forth between
    an inequality representation  and a generator (i.e. vertex and ray)
    representation of a polyhedron with cdd.  Also, cdd can solve a linear
    programming problem, i.e. a problem of maximizing and minimizing
    a linear function over P.
