  MATLAB/Octave version 4.2.2.
  Test cosine_transform().

cosine_transform_test01():
  cosine_transform_data() does a cosine transform of data
  defined by a vector.

  Apply the transform, then its inverse.
  Let R be a random N vector.
  Let S be the transform of D.
  Let T be the transform of E.
  Then R and T will be equal.
