y triangulation associated with the
      generators.  Moreover, the nearest-neighbor search and
      centroid computation are carried out efficiently using MATLAB's
      Delaunay search and rapid array accumulation.  The calling
      sequence is:
      <blockquote>
        [ p, t ] = cvt_square_uniform ( n, sample_num, delaunay_display )
      </blockquote>
      <ul>
        <li>
          <b>N</b>, the number of generators.
        </li>
        <li>
          <b>SAMPLE_NUM</b>, the number of sample p
