  Python version: 3.8.10
  Test laguerre_rule().

laguerre_rule():
  Compute a Gauss-Laguerre rule for approximating
    Integral ( a <= x < +oo ) exp(-b*(x-a)) f(x) dx
  of order ORDER.

  The user specifies ORDER, A, B, and FILENAME.

  ORDER is the number of points.
  A is the left endpoint (typically 0).
  B is the exponential scale factor (typically 1).
  FILENAME is used to generate 3 files:
  * filename_w.txt - the weight file
  * filename_x.txt - the abscissa file.
  * filename_r.txt - the region file.

  ORDER =  4
  A =  0.0
  B =  1.0
  FILENAME = "lag_o4".
  abscissas saved as "lag_o4_x.txt"
  weights saved as "lag_o4_w.txt"
  region saved as "lag_o4_r.txt"
