NAME

  Module generic_function_3p

USAGE

  use generic_function_3p

DESCRIPTION

  This module contains the generic routines to compute the
  three point functions in n and n+2 dimensions

OUTPUT

  It exports two public routines:
  * f3p(_sc)     -- a function to compute the three point function in n dimensions
  * f3p_np2(_sc) -- a function to compute the three point function in n+2 dimensions
    Calling the functions with _sc returns a real array. These calls will not be cached.

USES

  * precision (src/module/precision_golem.f90)
  * matrice_s (src/kinematic/matrice_s.f90) ( only : dim_s, b_ref )
  * s_matrix_type (src/module/s_matrix_type.f90)
  * array (src/module/array.f90)
  * tri_croissant (src/module/tri.f90)
  * constante (src/module/constante.f90)
  * function_3p1m (src/integrals/three_point/function_3p1m.f90)
  * function_3p2m (src/integrals/three_point/function_3p2m.f90)
  * function_3p3m (src/integrals/three_point/function_3p3m.f90)
  * cache (src/module/cache.f90)
  * equal (src/module/equal.f90)
