svd_circle_test():
  MATLAB/Octave version 9.8.0.1380330 (R2020a) Update 2
  Test svd_circle().

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:
   -0.8507    0.5257
   -0.5257   -0.8507

  Left singular vectors are columns of U:
   -0.9732   -0.2298
   -0.2298    0.9732

  Aspect ratio of ellipse will be 6.8541
  Slope of ellipse will be 0.236068
