COSINE_TRANSFORM_TEST
  FORTRAN90 version.
  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.
