<h3 class="section">4.5 Guru Interface</h3>

<p><a name="index-guru-interface-239"></a>
The &ldquo;guru&rdquo; interface to FFTW is intended to expose as much as possible
of the flexibility in the underlying FFTW architecture.  It allows one
to compute multi-dimensional &ldquo;vectors&rdquo; (loops) of multi-dimensional
transforms, where each vector/transform dimension has an independent
size and stride.
<a name="index-vector-240"></a>One can also use more general complex-number formats, e.g. separate real
and imaginary arrays.

   <p>For those users who require the flexibility of the guru interface, it is
important that they pay special attention to the documentation lest they
shoot themselves in the foot.
