`#include <CGAL/Barycentric_coordinates_2/Discrete_harmonic_2.h>`

## Definition

The class `Discrete_harmonic_2` implements 2D discrete harmonic coordinates (.

[2],[8],[1] ). This class is parameterized by a traits class `Traits`, and it is used as a coordinate class to complete the class `Generalized_barycentric_coordinates_2`. For a polygon with three vertices (triangle) it is better to use the class `Triangle_coordinates_2`. Discrete harmonic coordinates can be computed exactly. By definition, they do not necesserily give positive values.

Template Parameters

  Traits | must be a model of the concepts `BarycentricTraits_2` and `PolygonTraits_2`.

Is Model Of:
  `BarycentricCoordinates_2`

Precondition
  The provided polygon is strictly convex.

Examples:
  Barycentric_coordinates_2/Discrete_harmonic_coordinates_example.cpp.
