<h3 class="section">31.3 Transform Functions</h3>
<p>This sections describes the actual functions performing the discrete
wavelet transform. Note that the transforms use periodic boundary
conditions. If the signal is not periodic in the sample length then
spurious coefficients will appear at the beginning and end of each level
of the transform.
