      Description

      This is about integrating a f in [c, Inf] or in [-Inf, c]

      Gauss-Laguerre (GL) can be used to integrate between [0, Inf]
      http://en.wikipedia.org/wiki/Gauss%E2%80%93Laguerre_quadrature

      With the change of variables using f(g)
      where g = -x
      GL can be used to integrate in [-Inf,0]

      With another change of variables:
      g = x+c
      one could integrate in [c, Inf]
