fftw3: Guru Interface

 
 4.5 Guru Interface
 ==================
 
 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.  One can also use more general complex-number formats,
 e.g.  separate real and imaginary arrays.
 
    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.
