NAME

  Function f1p

USAGE

  real_dim4 = f1p(s_mat_p,b_pro,parf1)

DESCRIPTION

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

INPUTS

  * s_mat_(r/c/p) -- a real/complex (type ki)/type(s_matrix_poly) array of rank 2, 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

SIDE EFFECTS

  No side effect

RETURN VALUE

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