svd_circle_test():
  MATLAB/Octave version 5.2.0
  Test svd_circle().
  Map points x on unit circle to A*x
    Matrix A:
   3   2
   1   0

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

  Matrix A:

   3   2
   1   0
  Singular values of A are 3.702459 and 0.540182
  Right singular vectors are columns of V:
  -0.85065   0.52573
  -0.52573  -0.85065
  Left singular vectors are columns of U:
  -0.97325  -0.22975
  -0.22975   0.97325
  Aspect ratio of ellipse will be 6.8541
  Slope of ellipse will be 0.236068
