NAME
Module generic_function_2p
USAGE
use generic_function_2p
DESCRIPTION
This module contains the generic routines to compute the two point functions in n and n+2 dimensions
OUTPUT
It exports two public routine: * f2p -- a function to compute the two point function in n dimensions * f2p_np2 -- a function to compute the two point function in n+2 dimensions
USES
* precision (src/module/precision.f90) * array (src/module/array.f90) * logarithme (src/module/z_log.f90) * tri_croissant (src/module/tri.f90) * constante (src/module/constante.f90) * sortie_erreur (src/module/sortie_erreur.f90) * parametre (src/module/parametre.f90) * function_2p0m_1mi (src/integrals/two_point/function_2p0m_1mi.f90) * function_2p_m1m2 (src/integrals/two_point/function_2p_m1m2.f90) * s_matrix_type (src/module/s_matrix_type.f90)
