svd_sphere_test():
  MATLAB/Octave version 5.2.0
  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:
  -0.604629   0.273256   0.748167
  -0.725676   0.198242  -0.658858
  -0.328356  -0.941292   0.078432
  Left singular vectors are columns of U:
  -0.230357  -0.396071  -0.888855
  -0.607284  -0.655208   0.449343
  -0.760356   0.643297  -0.089596
