  * 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)

NAME

  Function f2p

USAGE

  cmplx_dim2 = f2p(s_mat_p,b_pro,parf1,parf2)

DESCRIPTION

  This function computes the generic two point function in n dimensions, 
  with or without Feynman parameters in the numerator

INPUTS

  * s_mat -- a derived type s_matrix_poly, the S matrix
  * b_pro -- an integer which represents the set of the four unpinched
    propagators
  * parf1 -- an integer (optional), the label of the one Feynman parameter
  * parf2 -- an integer (optional), the label of the second Feynman parameter

SIDE EFFECTS

  No side effect

RETURN VALUE

  It returns a complex (type ki) array of rank 1 and shape 2
