cannam@127 81
cannam@127 82 <p>The &ldquo;guru&rdquo; interface to FFTW is intended to expose as much as possible
cannam@127 83 of the flexibility in the underlying FFTW architecture. It allows one
cannam@127 84 to compute multi-dimensional &ldquo;vectors&rdquo; (loops) of multi-dimensional
cannam@127 85 transforms, where each vector/transform dimension has an independent
cannam@127 86 size and stride.
cannam@127 87 <a name="index-vector"></a>
cannam@127 88 One can also use more general complex-number formats, e.g. separate real
cannam@127 89 and imaginary arrays.
cannam@127 90 </p>
cannam@127 91 <p>For those users who require the flexibility of the guru interface, it is
cannam@127 92 important that they pay special attention to the documentation lest they
cannam@127 93 shoot themselves in the foot.
