问题解决了，原来matdyn.x有集成lambda.x的功能。相对于每个高斯展宽的a2f(w)都算出来了。

  ! INPUT from standard input:
  !    emax  degaussq  ngaussq
  !    nks
  !    q(1,1)    q(2,1)    q(3,1)    wk(1)
  !      ...       ...       ...      ...
  !    q(1,nks)  q(2,nks)  q(3,nks)  wk(nks)
  !    filelph(1)
  !     ...
  !    filelph(nks)
  !
  ! emax (THz)    : alpha2F is plotted from 0 to "emax" in "nex" steps
  ! degaussq (THz): gaussian smearing for sum over q
  !                 NB: not the same used in phonon !
  ! ngaussq       : 0 for simple gaussian, 1 for Methfessel-Paxton etc.
  ! nks           : number of q-points used in the sum
  ! q, wk         : q-points and weights
  ! filelph       : output files from phonon, one for each q-point
  !                 May contain "nsig" calculations done with different
  !                 broadenings for the sum over k - all of them are used
  !
  ! OUTPUT in xmgr-readable format: files 'lambda.dat' and 'alpha2F.dat'
  !
