|
|
<p>The “guru” interface to FFTW is intended to expose as much as possible
|
|
of the flexibility in the underlying FFTW architecture. It allows one
|
|
to compute multi-dimensional “vectors” (loops) of multi-dimensional
|
|
transforms, where each vector/transform dimension has an independent
|
|
size and stride.
|
|
<span id="index-vector"></span>
|
|
One can also use more general complex-number formats, e.g. separate real
|
|
and imaginary arrays.
|
|
</p>
|
|
<p>For those users who require the flexibility of the guru interface, it is
|
|
important that they pay special attention to the documentation lest they
|
|
shoot themselves in the foot.
