Cluster FFT Descriptor Configuration Functions

There are two functions in this category: the value setting function
DftiSetValueDM
sets one particular configuration parameter to an appropriate value, the value getting function
DftiGetValueDM
reads the value of one particular configuration parameter.
Some configuration parameters used by cluster FFT functions originate from the conventional FFT interface (see Configuration Settings for details).
Other configuration parameters are specific to the cluster FFT. Integer values of these parameters have type
MKL_LONG
. The exact type of the configuration parameters being floating-point scalars is
float
or
double
. The configuration parameters whose values are named constants have the
enum
type
. They are defined in the
mkl_cdft.h
header file
.
Names of the configuration parameters specific to the cluster FFT interface have prefix
CDFT
.
