| <p>Recall that the FFTW API is divided into three parts<a id="DOCF6" href="#FOOT6"><sup>6</sup></a>: the <em>basic interface</em>
 | |
| computes a single transform of contiguous data, the <em>advanced
 | |
| interface</em> computes transforms of multiple or strided arrays, and the
 | |
| <em>guru interface</em> supports the most general data layouts,
 | |
| multiplicities, and strides.  This section describes the basic
 | |
| interface, which we expect to satisfy the needs of most users.
