Description
The
vslConvSetStart
/
vslCorrSetStart
routine sets the value of the parameter
start
for the operation of convolution or correlation. In a one-dimensional case, this parameter points to the first element in the mathematical result that should be stored in the output array. In a multidimensional case,
start
is an array of indices and its length is equal to the number of dimensions specified by the parameter
dims
. For more information about the definition and effect of this parameter, see Data Allocation.
During the initial task descriptor construction, the default value for
start
is undefined and this parameter is not used. Therefore the only way to set and use the
start
parameter is via assigning it some value by one of the
vslConvSetStart
/
vslCorrSetStart
routines.
