<h3 class="section">4.4 Advanced Interface</h3>

<p><a name="index-advanced-interface-231"></a>
FFTW's &ldquo;advanced&rdquo; interface supplements the basic interface with four
new planner routines, providing a new level of flexibility: you can plan
a transform of multiple arrays simultaneously, operate on non-contiguous
(strided) data, and transform a subset of a larger multi-dimensional
array.  Other than these additional features, the planner operates in
the same fashion as in the basic interface, and the resulting
<code>fftw_plan</code> is used in the same way (see <a href="Using-Plans.html#Using-Plans">Using Plans</a>).
