Type Alias

vDSP_DFT_Setup

An opaque type that contains setup information for a given DFT transform.

Declaration

typealias vDSP_DFT_Setup = OpaquePointer

Discussion

A setup object can be allocated with vDSP_DFT_zop_CreateSetup(_:_:_:) or vDSP_DFT_zrop_CreateSetup(_:_:_:) and destroyed with vDSP_DFT_DestroySetup(_:). The setup object includes, among other things, precomputed tables used in computing a DFT of the specified size.
