| 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> | |
| 61 computes a single transform of contiguous data, the <dfn>advanced | |
| 62 interface</dfn> computes transforms of multiple or strided arrays, and the | |
| 63 <dfn>guru interface</dfn> supports the most general data layouts, | |
| 64 multiplicities, and strides. This section describes the the basic | |
| 65 interface, which we expect to satisfy the needs of most users. | |
