|
<p>FFTW’s “advanced” interface supplements the basic interface with four
|
||
|
|
new planner routines, providing a new level of flexibility: you can plan
|
||
|
|
a transform of multiple arrays simultaneously, operate on non-contiguous
|
||
|
|
(strided) data, and transform a subset of a larger multi-dimensional
|
||
|
|
array. Other than these additional features, the planner operates in
|
||
|
|
the same fashion as in the basic interface, and the resulting
|
||
|
|
<code>fftw_plan</code> is used in the same way (see <a href="Using-Plans.html">Using Plans</a>).
