<div class="block">Implements the <a href="http://www.archive.chipcenter.com/dsp/DSP000517F1.html">Fast Hadamard Transform</a> (FHT).
 Transformation of an input vector x to the output vector y.
 <p>
 In addition to transformation of real vectors, the Hadamard transform can
 transform integer vectors into integer vectors. However, this integer transform
 cannot be inverted directly. Due to a scaling factor it may lead to rational results.
