The discrete Fourier transform to be performed is defined by the creation of a descriptor class, with the associated configuration parameters, described in Configuration Parameters and Enums. Once the descriptor class is defined and commit is called and provided with a sycl::queue
to define the device and context, it can be used for computing the forward and/or backward transformations. The available data storage formats for the various configurations are described in Storage Formats.
