60 The “guru” 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 “vectors” (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.
