								<p>FFTW’s “advanced” interface supplements the basic interface with four
							 | 
						||
| 
								 | 
							
								new planner routines, providing a new level of flexibility: you can plan
							 | 
						||
| 
								 | 
							
								a transform of multiple arrays simultaneously, operate on non-contiguous
							 | 
						||
| 
								 | 
							
								(strided) data, and transform a subset of a larger multi-dimensional
							 | 
						||
| 
								 | 
							
								array.  Other than these additional features, the planner operates in
							 | 
						||
| 
								 | 
							
								the same fashion as in the basic interface, and the resulting
							 | 
						||
| 
								 | 
							
								<code>fftw_plan</code> is used in the same way (see <a href="Using-Plans.html">Using Plans</a>).
