cannam@127 82 <p>Recall that the FFTW API is divided into three parts<a name="DOCF6" href="#FOOT6"><sup>6</sup></a>: the <em>basic interface</em>
cannam@127 83 computes a single transform of contiguous data, the <em>advanced
cannam@127 84 interface</em> computes transforms of multiple or strided arrays, and the
cannam@127 85 <em>guru interface</em> supports the most general data layouts,
cannam@127 86 multiplicities, and strides. This section describes the the basic
cannam@127 87 interface, which we expect to satisfy the needs of most users.
