<longdescription>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 >= 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.</longdescription>
