4.3 Basic Interface

Chris@42: Chris@42: Chris@42:

Recall that the FFTW API is divided into three parts6: the basic interface Chris@42: computes a single transform of contiguous data, the advanced Chris@42: interface computes transforms of multiple or strided arrays, and the Chris@42: guru interface supports the most general data layouts, Chris@42: multiplicities, and strides. This section describes the the basic Chris@42: interface, which we expect to satisfy the needs of most users. Chris@42:
