svd_circle_test():
  python version: 3.10.12
  numpy version:  1.26.4
  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 3.702459173643833 and 0.5401815134754528
  Right singular vectors are columns of V:
[[-0.85065081  0.52573111]
 [-0.52573111 -0.85065081]]
  Left singular vectors are columns of U:
[[-0.97324899 -0.22975292]
 [-0.22975292  0.97324899]]
  Aspect ratio of ellipse will be 6.8541019662496865
  Slope of ellipse will be 0.2360679774997897
