Chris@10 60 The &ldquo;guru&rdquo; interface to FFTW is intended to expose as much as possible
Chris@10 61 of the flexibility in the underlying FFTW architecture. It allows one
Chris@10 62 to compute multi-dimensional &ldquo;vectors&rdquo; (loops) of multi-dimensional
Chris@10 63 transforms, where each vector/transform dimension has an independent
Chris@10 64 size and stride.
Chris@10 65 <a name="index-vector-240"></a>One can also use more general complex-number formats, e.g. separate real
Chris@10 66 and imaginary arrays.
Chris@10 67
Chris@10 68 <p>For those users who require the flexibility of the guru interface, it is
Chris@10 69 important that they pay special attention to the documentation lest they
Chris@10 70 shoot themselves in the foot.
