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