Parameters

pSrc

Pointer to the source vector.

pDst

Pointer to the destination vector.

len

Number of elements of the vector.

maskSize

Size of the mask.

Description

This function sets each element in the destination vector pDst as the sum of maskSize elements of the source vector pSrc. The computation is performed as follows:
