Description
Each of the vslConvExecX1D/vslCorrExecX1D routines computes convolution or correlation of one-dimensional (assuming that dims =1) data provided by the arrays x and y and then stores the results in the array z. These routines represent a special version of the operation, which expects that the first operand vector was set on the task construction stage.
Parameters of the operation are read from the task descriptor created previously by a corresponding vslConvNewTaskX1D/vslCorrNewTaskX1D constructor and pointed to by task. If task is NULL, no operation is done.
Using this form of execution routines is recommended when you need to compute multiple one-dimensional convolutions or correlations with the same data vector in array x against different vectors in array y. This helps improve performance by eliminating unnecessary overhead in repeated computation of intermediate data required for the operation.
