svd_sphere_test():
  MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2
  Test svd_sphere().

svd_sphere():
  Given a matrix A,
  plot points x on the unit sphere, and
  the images A*x of those points.
  Show right singular vectors V
  and their images, the scaled left singular vectors U.

  Matrix A:

     1     2     3
     4     5     6
     7     8     0

  Singular values of A are 13.201459, 5.438757 and 0.376047
  Right singular vectors are columns of V:
   -0.6046    0.2733    0.7482
   -0.7257    0.1982   -0.6589
   -0.3284   -0.9413    0.0784

  Left singular vectors are columns of U:
   -0.2304   -0.3961   -0.8889
   -0.6073   -0.6552    0.4493
   -0.7604    0.6433   -0.0896
