## Detailed Description

A linear expression.

An object of the class Linear_Expression represents the linear expression

where is the dimension of the vector space, each is the integer coefficient of the -th variable and is the integer for the inhomogeneous term.

How to build a linear expression.

Linear expressions are the basic blocks for defining both constraints (i.e., linear equalities or inequalities) and generators (i.e., lines, rays, points and closure points). A full set of functions is defined to provide a convenient interface for building complex linear expressions starting from simpler ones and from objects of the classes Variable and Coefficient: available operators include unary negation, binary addition and subtraction, as well as multiplication by a Coefficient. The space dimension of a linear expression is defined as the maximum space dimension of the arguments used to build it: in particular, the space dimension of a Variable `x` is defined as `x.id()+1`, whereas all the objects of the class Coefficient have space dimension zero.

Example
  The following code builds the linear expression , having space dimension :
  Linear_Expression e = 4*x - 2*y - z + 14;
  Another way to build the same linear expression is:
  Linear_Expression e1 = 4*x;
  Linear_Expression e2 = 2*y;
  Linear_Expression e3 = z;
  Linear_Expression e = Linear_Expression(14);
  e += e1 - e2 - e3;
  Note that `e1`, `e2` and `e3` have space dimension 1, 2 and 3, respectively; also, in the fourth line of code, `e` is created with space dimension zero and then extended to space dimension 3 in the fifth line.

Permutes the space dimensions of the expression.

Parameters

  cycle | A vector representing a cycle of the permutation according to which the space dimensions must be rearranged.

bool Parma_Polyhedra_Library::Linear_Expression::is_equal_to | ( | const Linear_Expression & | x | ) | const
| inline

Returns `true` if *this is equal to `x`. Note that (*this == x) has a completely different meaning.

void Parma_Polyhedra_Library::Linear_Expression::normalize | ( |  | ) |
| inline

Normalizes the modulo of the coefficients and of the inhomogeneous term so that they are mutually prime.

Computes the Greatest Common Divisor (GCD) among the coefficients and the inhomogeneous term and normalizes them by the GCD itself.
