Type Alias

vDSP_DFT_Setup

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

Declaration

typedef struct vDSP_DFT_SetupStruct *vDSP_DFT_Setup;

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.
