FFT Interface
The FFT functions are provided with the Fortran and C interfaces.
Intel® oneAPI Math Kernel Library
The materials presented in this
section
assume the availability of native complex types in C as they are specified in C9X.
To use the FFT functions, you need to
include
.
mkl_dfti.h
in your C code The C interface provides the
DFTI_DESCRIPTOR_HANDLE
type, named constants of two enumeration types
DFTI_CONFIG_PARAM
and
DFTI_CONFIG_VALUE
, and functions, some of which accept different numbers of input arguments.
The current version of the library may not support some of the FFT functions or functionality. You can find the complete list of the implementation-specific exceptions in the Release Notes.
