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
