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.
