Output Parameters
Name | Type | Description |
|---|---|---|
z | const float[] for vslsConvExec1D and vslsCorrExec1D ,const double[] for vsldConvExec1D and vsldCorrExec1D ,const MKL_Complex8[] for vslcConvExec1D and vslcCorrExec1D ,const MKL_Complex16[] for vslzConvExec1D and vslzCorrExec1D | Pointer to the array that stores output data.

Description
Each of the
vslConvExec1D
/vslCorrExec1D
routines computes convolution or correlation of the data provided by the arrays x
and y
and then stores the results in the array z
. These routines represent a special one-dimensional version of the operation, assuming that the value of the parameter dims
is 1. Using this version of execution routines can help speed up performance in case of one-dimensional data.Parameters of the operation are read from the task descriptor created previously by a corresponding
vslConvNewTask1D
/vslCorrNewTask1D
constructor and pointed to by task
. If task
is NULL
, no operation is done.
