vslConvExecX/vslCorrExecX

Computes convolution or correlation for multidimensional case with the fixed first operand vector.

Syntax

status = vslsConvExecX(task, y, ystride, z, zstride);

status = vsldConvExecX(task, y, ystride, z, zstride);

status = vslcConvExecX(task, y, ystride, z, zstride);

status = vslzConvExecX(task, y, ystride, z, zstride);

status = vslsCorrExecX(task, y, ystride, z, zstride);

status = vslcCorrExecX(task, y, ystride, z, zstride);

status = vslzCorrExecX(task, y, ystride, z, zstride);

status = vsldCorrExecX(task, y, ystride, z, zstride);

Description

Each of the vslConvExecX/vslCorrExecX 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 version of the operation, which assumes that the first operand vector was set on the task construction stage and the task object keeps the pointer to the array x.

Parameters of the operation are read from the task descriptor created previously by a corresponding vslConvNewTaskX/vslCorrNewTaskX 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 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.
