81 <p>The &ldquo;guru&rdquo; interface to FFTW is intended to expose as much as possible
82 of the flexibility in the underlying FFTW architecture. It allows one
83 to compute multi-dimensional &ldquo;vectors&rdquo; (loops) of multi-dimensional
84 transforms, where each vector/transform dimension has an independent
85 size and stride.
86 <a name="index-vector"></a>
87 One can also use more general complex-number formats, e.g. separate real
88 and imaginary arrays.
89 </p>
90 <p>For those users who require the flexibility of the guru interface, it is
91 important that they pay special attention to the documentation lest they
92 shoot themselves in the foot.
