60 Recall that the FFTW API is divided into three parts<a rel="footnote" href="#fn-1" name="fnd-1"><sup>1</sup></a>: the <dfn>basic interface</dfn>
|
|
Chris@19
|
61 computes a single transform of contiguous data, the <dfn>advanced
|
|
Chris@19
|
62 interface</dfn> computes transforms of multiple or strided arrays, and the
|
|
Chris@19
|
63 <dfn>guru interface</dfn> supports the most general data layouts,
|
|
Chris@19
|
64 multiplicities, and strides. This section describes the the basic
|
|
Chris@19
|
65 interface, which we expect to satisfy the needs of most users.
