cannam@95: The “guru” interface to FFTW is intended to expose as much as possible cannam@95: of the flexibility in the underlying FFTW architecture. It allows one cannam@95: to compute multi-dimensional “vectors” (loops) of multi-dimensional cannam@95: transforms, where each vector/transform dimension has an independent cannam@95: size and stride. cannam@95: One can also use more general complex-number formats, e.g. separate real cannam@95: and imaginary arrays. cannam@95: cannam@95:
For those users who require the flexibility of the guru interface, it is cannam@95: important that they pay special attention to the documentation lest they cannam@95: shoot themselves in the foot. cannam@95: cannam@95:
