GEN_LAGUERRE_RULE
  MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2

  Compute a generalized Gauss-Laguerre rule for approximating
    Integral ( a <= x < oo ) |x-a|^ALPHA exp(-B*(x-a)) f(x) dx
  of order ORDER.

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

  ORDER is the number of points.
  ALPHA is the exponent of |X|.
  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
  ALPHA = 0.500000
  A = 0.000000
  B = 1.000000
  FILENAME = "gen_lag_o4_a0.5".

  Creating quadrature files.

  "Root" file name is   "gen_lag_o4_a0.5".

  Weight file will be   "gen_lag_o4_a0.5_w.txt".
  Abscissa file will be "gen_lag_o4_a0.5_x.txt".
  Region file will be   "gen_lag_o4_a0.5_r.txt".

GEN_LAGUERRE_RULE:
  Normal end of execution.
