annulus_grid_test():
  MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2
  Test annulus_grid().

annulus_grid_test01():
  annulus_grid() defines a grid of points
  with N+1 points on a horizontal or vertical radius,
  based on any annulus.

  We use N = 20
  Inner radius R1 = 1.000000
  Outer radius R2 = 2.000000
  Center C = (1.000000,5.000000)

  Number of grid points will be 980

  First 20 points:
    2.0732    5.0000
   -0.0732    5.0000
    2.1707    5.0000
