DFTI_PLACEMENT
By default, the computational functions overwrite the input data with the output result. That is, the default setting of the configuration parameter
DFTI_PLACEMENT
is
DFTI_INPLACE
. You can change that by setting it to
DFTI_NOT_INPLACE
.
When the configuration parameter is set to
DFTI_NOT_INPLACE
, the input and output data sets must have no common elements.
