-Polyhedra Module
-================
-
-Polyhedron class allows users to build and inspect polyherons. Polyhedron inherits all methods from the :class:`Domain` class.
-
-.. py:class:: Polyhedron(Domain)
-
- .. py:method:: __new__(cls, equalities=None, inequalities=None)
-
- Create and return a new Polyhedron from a string or list of equalities and inequalities.
-
- .. attribute:: equalities
-
- Returns a list of the equalities in a polyhedron.
-
- .. attribute:: inequalities
-
- Returns a list of the inequalities in a polyhedron.
-
- .. attribute:: constraints
-
- Returns a list of the constraints of a polyhedron.
-
- .. py:method:: make_disjoint(self)
-
- Returns a polyhedron as a disjoint.
-
- .. py:method:: isuniverse(self)
-
- Return ``True`` if a polyhedron is the Universe set.
-
- .. py:method:: aspolyhedron(self)
-
- Return the polyhedral hull of a polyhedron.
-
- .. py:method:: __contains__(self, point)
-
- Report whether a polyhedron constains an integer point
-
- .. py:method:: subs(self, symbol, expression=None)
-
- Subsitute the given value into an expression and return the resulting
- expression.
-
- .. py:method:: fromstring(cls, string)
-
- Create and return a Polyhedron from a string.
-
-
-To create a polyhedron, the user can use the following functions to define equalities and inequalities as the constraints.
-
-.. py:function:: Eq(left, right)
-
- Returns a Polyhedron instance with a single constraint as *left* equal to *right*.
-
-.. py:function:: Ne(left, right)
-
- Returns a Polyhedron instance with a single constraint as *left* not equal to *right*.
-
-.. py:function:: Lt(left, right)
-
- Returns a Polyhedron instance with a single constraint as *left* less than *right*.
-
-.. py:function:: Le(left, right)
-
- Returns a Polyhedron instance with a single constraint as *left* less than or equal to *right*.
-
-.. py:function:: Gt(left, right)
-
- Returns a Polyhedron instance with a single constraint as *left* greater than *right*.
-
-.. py:function:: Ge(left, right)
-
- Returns a Polyhedron instance with a single constraint as *left* greater than or equal to *right*.
