status
int
Set to
VSL_STATUS_OK
if the task is executed successfully or set to non-zero error code otherwise.
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.
